摘      要：Pin fins are widely used in applications where effective heat transfer is *** compact design,high surface area,and efficient heat transfer characteristics make them a practical choice for many thermal management *** for a high heat transfer rate and lightweight application,aerofoil shape pin fins are a good *** work focuses on an experimental model analysis of pin-fins with aerofoil *** results were evaluated between perforation,no perforation,inline,and staggered fin *** is used to make the pin fins *** experiment is carried out inside a wind tunnel,and the heat supply varies between 500 to 3000 *** electric heater,fan,anemometer,thermocouple,pressure transmitter,data logger,and computer system were used for this *** friction factor,thermal efficiency,performance efficacy,and pressure drop of a pin fin aerofoil shape have been assessed.A comparison study was carried out with and without perforations and inline and staggered *** terms of overall efficacy,different aerofoil shape pin fin arrays achieve values varying between 1.8 and *** acquired data demonstrate that perforated staggered configurations perform 10%better than ***,the pressure drop is reduced by 50%in staggered *** empirical correlation of Dittus-Bolter and Blasius correlations was used to validate the experimental heat dissipation enhancement factor requirements of Nusselt number and friction *** validation of the experiment using correlation has been completed ***,experimental results prove that aerofoil pin-fin arrays can be used successfully for applications like the electronics industry,heat exchangers and gas turbine blade cooling.
