The effect of using different based nanofluids on trapezoidal microchannels cooling performance

Numerical investigations are performed to explore the aluminum trapezoidal microchannel heat sink (MCHS) cooling benefits by using different types of base nanofluids for laminar flow. Considering a diamond nanoparticle with particle volume fraction of 2% was mixed in four different base fluids inclu...
