Comparative Studies on Conjugate Mixed Convection in Perforated Fins

The present paper reports on the results of experimental study on combined conduction-mixed convection of pin-fins with and without perforations having uniform internal heat generation. Different types of fin configurations viz. , solid, hollow, solid pin fin with four perforations, solid fin with knurling and solid pin fin with a single perforation having equal weight are considered for the study. A comparative study has been done on the performance of fins used in various applications. An experimental set-up was designed and fabricated for the purpose. Further an effect heat transfer parameters on perforated fin were discussed in detail.
