A three-dimensional inverse design problem is examined in this thesis using a general purpose commercial code (CFD-ACE+) and the Levenberg-Marquardt Method (LMM) to estimate the optimal perforation diameters of perforated pin fins with different design variables. The study consists of three cases.
The objective of this thesis is to minimize the temperature difference between base and the environment (ΔT), and system pressure drop (ΔP) of the fin array and to obtain the optimal perforation diameters of pin fins. In design case #1, the optimal heat sink uses five parameters in the optimization design, in design case #2, four parameters are utilized to obtain the optimum heat sink module and in design case #3, only one parameter is considered in the design process.
Experiments are performed to show the validity of the present design results. Results show that the temperature difference between base and the environment (ΔT), and pressure drop (ΔP) of the original design heat sink module can be further reduced in the optimum heat sink modules with perforated pin fins. Moreover, the temperature distributions are very similar between the experimental and numerical data.
