Fins in Thermal Engineering from ANSYS (original) (raw)

Heat transfer by convection between a surface and the fluid surrounding can be increased by attaching to the surface called fins. The heat conducted through solids, walls, or boundaries has to be continuously dissipated to the surroundings or environment to maintain the system in a steady state condition. The cylinder of the engine is one of the key components of the vehicle and is prone to maximum temperature variation and thermal stress. To cool the cylinder, the cylinder fin is designed to improve the heat transfer rate. Thermal analysis is done on the engine cylinder fins; it is very useful to understand the heat dissipation in the cylinder. The idea applied in this project is to increase the heat dissipation rate by using intangible working fluid, just air. It is understood that the heat dissipation rate is increased by changing the surface region; therefore, it is very challenging to design such a huge complicated engine. In this project, the analysis of the engine fin is carried out for different geometries such as Rectangular, Triangular, convex, and Tapered fin. A 3D model is created in SolidWorks and analysis is done using ANSYS Software in steady state condition. The material used for the fin body is Al6063. The result is compared to find the best geometry which gives the maximum heat flux.

The Engine cylinder is one of the major automobile components, which is subjected to high temperature variations and thermal stresses. In order to cool the cylinder, fins are provided on the surface of the cylinder to increase the rate of heat transfer. By doing thermal analysis on the engine cylinder fins, it is helpful to know the heat dissipation inside the cylinder. We know that, by increasing the surface area we can increase the heat dissipation rate. The main aim of the present paper is to analyze the thermal properties by varying geometry, material of cylinder fins using Ansys work bench. Transient thermal analysis determines temperatures and other thermal quantities that vary over time. The variation of temperature distribution over time is of interest in many applications such as in cooling. The accurate thermal simulation could permit critical design parameters to be identified for improved life. Presently Material used for manufacturing fin body is Cast Iron. In this thesis, it is replaced by various types of aluminum alloys. By observing the analysis results, total heat flux is more for aluminum alloys than remaining cast iron, magnesium alloy materials for both condenser and evaporator. So aluminum alloy would be better for cylindrical fins.

When fuel is burned in an engine, heat is produced. Additional heat is also generated by friction between the moving parts. Approximately 30% of the energy released is converted into useful work while remaining 70% must be removed from the engine to surrounding, to prevent the parts from overheating. In an air-cooled I.C engine, extended surfaces called fins are provided at the periphery of engine cylinder to increase heat transfer rate. That is why the analysis of fin is important to increase the heat transfer rate. The main of aim of this work is to study different types of fins to improve heat transfer rate of cooling fins by changing cylinder fin geometry.

Fins are one of the important key cooling elements. The main purpose of pin fins is to increase the rate of heat transfer to the surroundings by improving convection. The transferred heat will exist in the form of conduction, convection and radiation. If the temperature coefficient of heat transfer increases, the cooling rate will also increase. The main objective of our project is to increase the rate of heat transfer in different types of fins with different shapes.3D models were designed in Catia and tested in Ansys. Use the developed fins in various applications.

The work is set to analysis the heat dissipation of fins by deviate its geometry in both uniform and non-uniform types, with different material compositions. The models are generated by varying the geometry such as rectangular and triangular. The models were created by using the software 3D Experience. The analysis was carried out by using ANSYS 18.1. The conventional Material used for manufacturing fin body is generally Aluminium Alloy 204 and Aluminium Alloy 6061.We Analysed Aluminium Alloy 6063 which has a higher thermal conductivity of 201-218 W/m-⁰C. After analysis, the performance parameters are compared with all types of geometries of different material compositions in Aluminium 6063.

To study different research papers related to thermal analysis of extended surfaces or projections of materials on the system (engine) called fins of air cooled IC engines. The fins are used to increase the heat transfer rate from the system to the surrounding by increasing the heat transfer area. Fins are used to cool various structures via the process of convection. Generally heat transfer by fins is basically limited by the design of the system. The heat transfer effect may be varied by changing material of different thermal conductivities, improvising engine geometry, increasing cross section area of fins, using perforations on fin and on CFD analysis of fins. Hence the aim of this paper is to study from different literature surveys that how heat transfer through extended surfaces and the heat transfer coefficient affected by changing cross-section this study is useful to know the better geometry and material for the fins for better engine cooling.

The engine is the heart of an automobile which is subjected to high temperature variation and thermal stresses. The high temperatures produced in the engine cylinder needs to be reduced for effective working of the engine. If the heat is not dissipated properly then it causes to development of the detonation and finally decrease the working efficiency hence, heat dissipation rate from the cylinder is one of the important task. These high temperatures are reduced by introducing the appropriate cooling mechanism air cooling, water cooling, oil cooling. An air cooled motorcycle engine release the heat produced by engine to the atmosphere through forced convection mode. Fins are provided on outer surface of the cylinder block. Fins are the extended surface which helps in dissipation of the heat generated in the engine. The heat dissipation depends upon the velocity of air, geometry of the fin and the thermal conductivity of the materials used. In this project an attempt is made to find out the thermal analysis and CFD simulation of cylinder block with fins for different materials like Al6061, Al2014, Al a380 and also changes are done in the design of fins to increase the heat dissipation rate. The changes made in the fins are increases the tip thickness and provides slots of different dimensions and shapes like rectangular slot, triangular slot, semicircular slot. The slot sizes are varied while keeping the fin size and the number of fins same. The 3D modelling is done on Creo 2.0software and the analysis part and CFD is done on ANSYS software for steady state condition. Results of the various analysis done shows that engine cylinder with aluminium alloy 2014 with semicircular slot of area 50 mm 2 dissipates more heat when air flows through the fins.
