DESIGN OPTIMISATION OF CYLINDER FINS WITH OR WITHOUT COATINGS

Abstract

Fins or extended surfaces have many applications in heat transfer such as air conditioning, refrigeration,
automobile, chemical processing equipment and electrical chips for increasing the heat transfer rate. Recently,
researchers and engineers in this field have been paying more attention to both energy conservation and equipment size
reduction due to energy crisis in the world.
So, optimizing the heat transfer is highly desired for effective energy utilization. Because the weight and
material cost of the extended surfaces are very important, fin dimensions should be optimized so that the least amount of
fin material be used to dissipate a given amount of heat flow, or alternatively that the highest dissipation rate be
obtained from a given volume of fin material.
The analysis is carried out for various models of the engine cylinder fins. The modeling is done in Creo
Parametric 2.0, thermal analysis is done in Ansys 15.0 (Workbench 15.0). The thermal analysis is performed to check for
the better material which can be used to the engine cylinder fins in order to increase the performance. With different
shapes and based on the results obtained the geometry that yielded the maximum beneficiary results was identified.
