Experimental Investigation of Convective Heat Transfer through Rough and Smooth Surfaced Aluminium 6063 Pin-Fin Apparatus

In reciprocating engines, transfer of heat is the primary task for increasing the engine efficiency and effectiveness rather than liquid cooling; the air cooling is most preferable for its simplicity. By increasing the contact surface and usage of high value heat transfer coefficient metals air cooling is highly possible compared to other metals aluminium fin heat exchanger provides better corrosion resistance due to a better galvanic balance of the materials and more cost effective. In this project, it is to enhance the cooling effect of aluminium 6063 by some design changes. Usually smooth surfaced aluminium 6063 alloy is used as heat exchangers here same aluminium 6063 alloy with rough surface fin has been tested. The flow can be promoted from laminar to turbulent which creates the high contact between air and the metal surface this is one of the heat transfer enhancement method used traditionally and not in practical applications. In this paper comparison has been made and applications had stated.
