Abstract
The Engine chamber is one of the essential engine components, that is subjected to over the top temperature differences and thermal stresses. Fins are set on the surface of the cylinder to improve the quantity of heat exchange by convection. When fuel is burned in an engine, heat is produced. Additional heat is also generated by friction between the moving parts. In 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 various researches done in past to improve heat transfer rate of cooling fins by changing cylinder fin geometry and material. In the present work, Experiments have been performed to discover the temperature variations inside the fins made in four kind geometries (plate Fins, Circular Pin fins, plate fins with holes, and draft Pin fins) and consistent state heat exchange examination has been studied utilizing a finite element software ANSYS to test and approve results. The temperature variations at various areas of fins models are evaluated by FEM and compared models of fins performance by heat flux and temperature variations obtained by experimentally in Analysis. The principle implemented in this project is to expand the heat dissipation rate by utilizing the wind flow. The main aim of the study is to enhance the thermal properties by shifting geometry, material, and design of fins.
Highlights
In normal cause, larger parts of an engine remain exposed to the atmospheric air
The Temperature and Total Heat Flux in thermal analysis compared with the plate Fins, Circular Pin fins, and plate fins with holes, draft Pin fins
These results as part of structural and thermal analysis are obtained for all three conditions i.e. plate Fins, Circular Pin fins, plate fins with holes, and draft Pin fins
Summary
Larger parts of an engine remain exposed to the atmospheric air. When the vehicles run, the air at certain relative velocity impinges upon the engine, and sweeps away its heat. For the guideline of conduction, convection, radiation of a fin arrangement optimized the quantity of heat it exchanges Increasing the temperature contrast between the fin setup and based upon surroundings, marginally expanding the convection heat transfer coefficient, or somewhat expanding the surface region of the fin design of the object enhance the heat exchange. This can be achieved by faster heat dissipation. By using the extended surfaces (Fins) we can improve the heat transfer rate from engine cylinder. Extended area on the cylinder surfaces is use to increase the surface area in contact with the fluid flowing around it
