Design, Thermal Analysis and Development of Extended Surfaces

The Engine cylinder is one of the major automobile component which is subjected to high temperature variations and thermal stresses. In order to cool the cylinder, fins are provided on the cylinder. The main aim of the project is to analyze the thermal properties by varying geometry, material (Cu, Al, Cast iron and Magnesium), distance between the fins and thickness of cylinder fins and optimize the heat transfer. The Fins models are created by varying thickness of the fins for rectangular and triangular geometry. The 3D modeling software used is Solid Works. Thermal analysis is done on the cylinder fins to determine variation temperature distribution. The analysis is done using ANSYS. By doing thermal analysis on the engine cylinder fins, it is helpful to know the heat dissipation inside the cylinder. The principle implemented in this project is to study and optimize the cooling rate and effectiveness of engine by introducing extended surfaces of varying size and cross sections. Analysis is carried out by varying temperatures on the surface of the cylinder upto 200ËšC and varying length from 26 mm to 33 mm. Input parameters such as heat transfer coefficient, thermal conductivity and thickness of fin are taken and output parameters such as rate of heat flow, efficiency and effectiveness are determined.
