Numerical analysis and parametric study of multilayered microchannel heat sinks

Advances in Mechanical Engineering, 2015
A three-dimensional solid–fluid conjugated model is used to investigate and optimize the performances of two-, three-, and four-layered microchannel heat sinks. In the optimization process, constraints of fixed total pumping power and fixed total channel

Methods and techniques of improving experimental testing for microfluidic heat sinks

Case Studies in Thermal Engineering, 2017
There exist numerous methods of experimentally testing designs for heat sinks in the laboratory, especially for microscale fluidic devices, which can lead to a problem for comparison between new studies and those in the literature. To explore this issue,
