Multi-factors Optimization Design of Pin-Fin Structure Using Respond Surface Method

摘要

This study aims to find out the optimized solution for coupled effects of parameters. Different turbulence models were studied and RSM (Response Surface Methodology) was the most appropriate one to deal with optimization of target and investigate interaction of different parameters. In design height and diameter of cylindrical pin-fin was adopted as control parameters, according to numerical simulation the thermal resistance and pressure loss of pin-fin heat sink indicated improving tendency with increasing the both parameters. Sensitivity analysis was conducted to investigate the correlation of two geometrical parameters to response target. Less head loss and better cooling efficiency were achieved from an optimized structure.
