碩士 / 國立成功大學 / 系統及船舶機電工程學系 / 103 / 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 positions and shapes for delta winglet vortex generators of heat sinks with different design variables.
The objective of this thesis is to minimize the average temperature on the base plate of heat sinks and to obtain the optimal positions and shapes for delta winglet vortex generators of heat sinks. The study consists of two cases. In case 1, Delta winglet vortex generators are used on a plate-fin heat sink to estimate the optimization design when the inlet velocity equal to 1.2, 1.8 and 2.4 m/s, respectively. In case 2, Delta winglet vortex generators are used on a pin-fin heat sink to estimate the optimization design when the inlet velocity equal to 1.2, 1.8 and 2.4 m/s, respectively.
Finally, these heat sink and vortex generators modules are carried on the experimental verification. The results of temperature distributions are very similar between the experimental and numerical data.
