FLOW SIMULATION AND PERFORMANCE PREDICTION OF CENTRIFUGAL PUMPS USING CFD-TOOL
With the aid of computational fluid dynamics, the complex internal flows in water pump impellers can be well predicted, thus facilitating the product development process of pumps. In this paper a commercial CFD code was used to solve the governing equations of the flow field. A 2-D simulation of turbulent fluid flow is presented to visualize the flow in a centrifugal pump, including the pressure and velocity distributions. The standard k- turbulence model and SIMPLEC algorithm were chosen for turbulence model and pressure-velocity coupling respectively. The simulation was steady and moving reference frame was used to consider the impeller-volute interaction. The head and efficiency at different flow rates are predicted and they agree well with those available in literature for similar pump. From the simulation results it was observed that the flow change has an important effect on the location and area of low pressure region behind the blade inlet and the direction of velocity at impeller inlet. From the study it was observed that FLUENT simulation results give good prediction of performance of centrifugal pump and may help to reduce the required experimental work for the study of centrifugal pump performance.
The Use of CFD for Flow Analysis and Performance Prediction of Centrifugal Pumps
This paper presents some user experience in using the commercial CFD code Fluent for pump flow field calculations. It demonstrates the use of the code with respect to simulating the flow within an industrial centrifugal pump and predicting the corresponding head-capacity curve. Throughout the paper, the CFD model of the selected pump is discussed. The pump with backward curved blades is modeled and meshed with unstructured grid. Quasi-steady calculations utilizing the k-ε turbulence model and the multi reference frame technique are performed for the design point as well as for a range of volume rates with a deviation of 50% from the design value but with similar flow patterns. The data obtained allow the analysis of the main phenomena existent in the pump, such as: pressure changes in the volute for different flow rates; and the incidence at the leading edge of the blade with different flow conditions.
Design and CFD Analysis of Centrifugal Pump

The purpose of this report is to identify /observe and determine the pattern of velocity profile and pressure distribution by using CFD simulation program after the 3D design and modeling of the pump is made using Vista CPD. We have also created a Solid model using Fusion 360 to get a clear idea of Centrifugal pump design. Basically, this report revolves around the idea of investigating the effect and distribution of velocity profile and pressure within a pump having the following specification, Head = 20 m, Flow rate = 100 m 3 /hr, and RPM = 2000. 3D Navier-Stokes equations were solved using ANSYS CFX. The standard k −εturbulence model was chosen for the turbulence model. From the design point of view, we have studied the effects of different parameters like rotational speed, volume flow rate etc on the impeller and volute. From the simulation results it was observed that the pressure increases gradually from impeller inlet to outlet. The static pressure on the pressure side is evidently larger than that on the suction side at the same impeller radius. In addition to this, it was observed that the velocity increases from the impeller inlet until it enters the volute casing. It then drops to a minimum value at the outlet region.
CFD Investigation on Three Turbulence Models for Centrifugal Pump Application
The Eurasia Proceedings of Science Technology Engineering and Mathematics
This paper highlight the influence of three numerical turbulence models on the convergence and the performance of flow simulation. The computational comparative study was realized using the COMSOL Multiphysics 5.5 code. Turbulence was generated numerically in a centrifugal water pump using the k−ϵ, k−ω and k−ω SST models. However, the geometry was performed on SolidWorks due to its complexity. The flow modelling was mainly based on the resolution of the stationary Navier-Stokes equations. The effects of the tested models on CFD numerical simulation were examined. It was found that the best calculation precision was obtained using the K−ω model, while the lowest was provided by the K−ω SST model. However, a very low calculation cost was obtained by the latter. As well as better pumping performance were recorded.

Computational Fluid Dynamics is most commonly used tool for simulation and analysis. 3-D numerical CFD tool is used for simulation of the flow field characteristics inside the turbo machinery. CFD simulation makes it possible to visualize the flow condition inside centrifugal pump. The present paper describes the head, power, efficiency and to evaluate the pump performance using the ANSYS FLUENT, a computational fluid dynamics simulation tool. These simulations of centrifugal pumps are strongly related to flow rate and pressure drop, which may occur in either the rotating runnerimpeller or the stationary parts of the centrifugal pumps. The numerical simulation can be used to detect the performance of centrifugal pump and to get safe range of operating at different flow rate and rotating speeds.

A Technical Review on Analysis of Centrifugal Pump
Centrifugal pumps are grossly used in chemical industries, oil refineries, sewage disposal systems, mines, food processing industries, power plants for the transportation of fluids. Hence it is required to find the geometric parameters and working conditions to achieve maximum head and efficiency without increasing the manufacturing cost. This paper evince the increasing use of computational fluid dynamics for the analysis of centrifugal pump, as there are various parameters which affect the performance of centrifugal pump it is necessary to analyze all the forces which are act on pump impeller such as drag and friction forces. CFD analysis is very useful to determine the amount of drag force acting on pump impeller when working with different fluids such as Newtonian and non-Newtonian fluids, as the amount of drag force increase than power requirement also increase results in poor performance. Therefore it is necessary to carry out CFD analysis on centrifugal pump maintain its performance in any condition.

In this work, the hydraulic and energetic performance of a centrifugal pump is studied in CFD (Computational Fluid Dynamics), to achieve optimization in its performance through a parametric analysis. Variations were made in pump parameters such as diameter, number of blades and speed of rotation, to study their influence over the general performance of the pump, by using a CFD package; the results obtained were validated in a test bench, to guarantee the prediction capacity of the simulations. In the same way, a theoretical analysis was carried out, comparing the results with the Euler equation and corrections with Stodola equation. An analysis of mesh independence was carried out, to optimize the simulation process and computational resources. The results allowed to conclude that the reduction in the thickness of the pump casing, which has the effect of a larger diameter of the impeller, leads to an increase in the effective head of the pump; similar results are obtained with the increase in the number of blades and the 1350 Jorge Duarte et al. increase in the speed of rotation, although in the latter case, it is less accentuated due to the reduction in volumetric efficiency.
