The effects of heights, attack angles of VGs inside a tube on heat transfer and flow behavior are investigated. CFD simulations, with and without VGs insert, are done for an air flow range (Reynolds numbers 6000 to 33000) and for a constant heat flux on the tube model surface. Four VGs are fitted in a circular pattern on the inner surface of the tube. We studied the characteristics of the delta winglet VGs for different attack angles and blockage ratios. The Nusselt number and friction factor results show the influence of the VGs insert on heat transfer and frictional factor. The maximum Nusselt number increment (Nu/Nu0) was achieved to be 1.75 while the maximum friction factor increment (f/f0) was 3.21. In order to understand the flow behavior and different vortices, path lines released by the VGs surface and details of the vortices are also studied.

The low percentages of women studying engineering around the world especially in northern America... more The low percentages of women studying engineering around the world especially in northern America is a well-known issue in higher education. Despite many efforts from academic institutions and industry, the number of women enrolled in undergraduate engineering programs in the United States has stagnated around 17-19 percent since 2003. However, in the Middle-Eastern GCC countries in general and in the United Arab Emirates UAE in particular, a different picture emerges. There has been significant progress in women enrolling in STEM programs, especially engineering, in the GCC over the past few years. In the case of the UAE, the vision of the government leadership, as evident in the constitution and in government initiatives provides some insight into some of the support leading to this phenomena. The Petroleum Institute PI in Abu Dhabi admitted its first cohort, of male students, 2001. Five years later, the institute opened its doors to female students. Initially, the numbers of enrolled female students were low as no on campus housing was available for them. In 2014 female dormitories became available and the number of female students surged. Over 63% of the 2020 class are female. This surge in interest by young Emirati women in engineering is of particular interest as all PI graduates begin their careers with the Abu Dhabi National Oil Company (ADNOC), in the Oil and gas industry, an industry with one of the lowest percentages of female employees. This paper examines the PI female students' performance. It also explores their motivation, expectations, career choice as well as the kind of support they receive. The findings shed some light on the reasons why they chose to pursue a career in the oil and gas industry, where they would be interested to work, and who encourages them. The discussion also examines if they feel that the oil and gas industry offers the same opportunities for female employees as for male employees and that women can reach top management positions within the oil and gas industry. It seems there are several factors contributing to the current increase in the percentage of women in engineering. It is probably a combination of factors such as the vision of the government and the motivation of the young women to serve their community and make their families proud.

While the weight loss caused by erosion–corrosion is known to depend on flow velocity, angle of impact, sand loading and size and target material properties, field operators often limit the flow rate based on a critical corrosion velocity to protect the equipment. This study investigates the effects of sand loading and flow velocity on weight loss associated with erosion–corrosion in a mild steel sample using a submerged impingement jet. The weight loss by erosion, corrosion and their interaction for a flow velocity range of 10 m/s to 20 m/s and sand loading range of 300 mg/L to 600 mg/L, in a seawater environment, are presented. The results showed that the weight loss by pure erosion and erosion–corrosion interaction increases linearly wi...

The programs were established in 1997 to serve the students from the surrounding rural areas and thus to serve as a vehicle to enhance the economic development of the region. Nearly a three-fourth of courses in the program are taught by the faculty at FSU, while the remaining are taught over interactive television by faculty at UMCP. Six students from the first batch graduated in May 2001. The challenges encountered in the process so far and the resulting modifications made are described.

The material degradation caused by erosion-corrosion in pipelines can result in a high cost of monitoring and maintenance and in major accidents. The process of erosion-corrosion consists of erosion, corrosion, and their interactions. Investigating and understanding how the erosion-corrosion process affects the degradation process in certain materials will allow for a reduction in economic loss and help prevent accidents. In this study, material loss due to erosioncorrosion of mild steel under impingement of sand-laden water at 90 ̊ impingement angle is investigated using a submerged impingement jet (SIJ) test. In particular, effects of jet velocity and sand loading on TWL due to erosion-corrosion, weight loss due to pure erosion and erosion-corrosion interactions, at a temperature of 29-33 °C in sea water environment (3.5% NaCl), are analyzed. The re...

An initial model of the pipe was constructed using experimental input-output data and system identification (SysID) techniques. The model derived through SysID showed a poor performance in predicting the vibration of the pipeline at locations other than that of the output sensor. Improvement of the SysID model was achieved using the Linear Quadratic Gaussian (LQG) observer-regulator modeling approach. While the hybrid model, combining both SysID and LQG, performed better, its transient response was not accurate. Further improvement to the model was achieved by incorporating a two degree of freedom, (2DOF) Proportional-Integral-Derivative (PID) to improve transient characteristics of the model. Experimental evaluation of the 2DOF PID assisted hybrid model showed good performance that far exceeded that of the hybrid model alone. The validity of the proposed approach was exp...

The model consists of three components integrated: Fluid Transport to describe the flowing fluid via Reynolds-Averaged Navier-Stokes equations with standard k-ε turbulence model, Particle Transport to describe the trajectories of the solid particles using Discrete Particle Modeling (DPM) and Particle Erosion to describe the erosion rate using Oka erosion model. The model is validated against experimental data for erosion in curved pipe of constant cross section. This study focuses at the geometrical effect of curved pipes, i.e. converging, constant cross section and diverging, on erosion. Both maximum erosion and locations where it occurs are identified. Results show that curved converging pipes suffer from high erosion rate concentrated especially in the outer wall of the curved section. Curved diverging pipes on the other hand has much lower erosion of erosion rate at least one order of m...

For each course’s nine areas of knowledge, competency, and skills, the research team reviewed the existing learning outcomes and related performance indicators with a focus on identifying linkages across disciplines as well as within the courses of a discipline. The team reviewed existing performance indicators for developmental progression from semester to semester for same discipline related courses (vertical alignment) and for different discipline courses within the same semester (horizontal alignment). The results of this work have led to recommendations for modifications of the initial indicators when incoherence was identified, and/or for new indicators based on best practices (identified through literature searches) when gaps were identified. It also led to recommendations for modifications of the level of emphasis within each course to ensure developmental progression. The exercise has led to a revised Sequence Performance Indicator Mapping for the knowledge, skills, and competencies across the six core courses.

The concept of sustainability has been widely accepted and is considered a desirable feature in any product or system that is being designed. Engineers play a vital role in the societal development and even they are characterized as the exploiters of potential for useful purpose. Perceptions on sustainability differ from culture to culture and from industry to industry. The concept of sustainability is usually introduced to students by mean of the University culture or by means of different introductory engineering courses. Most of the engineering programs have an introductory engineering design courses, where the sustainability module is placed. STPS 201 (Strategies for team based problem solving) is a three credit sophomore engineering design course at The Petroleum Institute which introduces the students to engineering design. This course is currently being looked to address the sustainability component which would serve to increase the awareness of sustainability, thereby fulfilling the ABET requirements for the program, objectives of the university sponsors, and finally the UAE 2020 vision. The objectives and visions are laid very clearly at the top but not much is done between the different levels to address the sustainability component. So a "bottom-up" approach is being used to embed the sustainability into the university curricula to meet the objectives and vision.

Reynolds number 19800, based on centerline velocity and channel half width. The large-scale flow field has been obtained by directly integrating the filtered, three-dimensional, tine-dependent, Davies-Stokes equations. The smallscale field motions were simulated through an eddy viscosity model. The calculations were carried out on the ILLIAC IV computer with up to 516,096 grid points. The computed flow field was used to study the statistical properties of the flow as well as its time-dependent features. The agreement of the computed mean velocity profile, turbulence statistics, and detailed flow structures with experimental data is good. The resolvable portion of the statistical correlations appearing in the Reynolds stress equations are calculated. Particular attention is given to the examination of the flow structure in the vicinity of the wall. I. Introduction Large-eddy simulation (LBS) is a relatively new approach to the calculation of turbulent flows. The basic idea stems from two experimental observations. First, the large-scale structure of turbulent flows varies greatly from flow to flow (e.g., jets vs. boundary layers) and consequently is difficult, if not impossible, to model in a general way. Second, the small-scale turbulence structures are nearly isotropic, very universal in character (Chapman, 1979) and hence such sore amenable to general modeling. In LBS, one actually calculates the large-scale notions in a time-dependent, three-*Portions of this work were carried out while the authors held NRC Research Associateships at Ames Research Center.

First, the large-scale structure of turbulent flows varies greatly from flow to flow (e.g., jets vs. boundary layers) and consequently is difficult, if not impossible, to model in a general way. Second, the small-scale turbulence structures are nearly isotropic, very universal in character (Chapman, 1979) and hence such sore amenable to general modeling. In LBS, one actually calculates the large-scale notions in a time-dependent, three-*Portions of this work were carried out while the authors held NRC Research Associateships at Ames Research Center.
