A study on heat transfer characteristics of fibonacci spiral microchannel heat sink

Abstract

A study on a Fibonacci spiral microchannel heat sink was carried out in the present work to predict thermal resistance and pressure drop of the model. The Computational Fluid Dynamics software (ANSYS Fluent 14) and Taguchi method were used to simulate and optimize the parameters of the Fibonacci spiral microchannel heat sinks. In addition, the Minitab 17 software was also used to analyze the simulated data. The result shows that the optimal design parameters can give good agreement of the overall thermal resistance and pressure drop (with the values 0.715/Wm², 15.53kPa, respectively.) were achieved for the design of the Fibonacci spiral micro-channel heat sink.
