Performance of water based CuO and Al2O3 nanofluids in a Cu–Be alloy heat sink with rectangular microchannels

Graphene nanoplatelets–silver hybrid nanofluids for enhanced heat transfer

“…Al 2 O 3 ,CuO, ZnO, silver and zirconia were typically used in many nanofluids compared to other kinds of metal oxide nanomaterials [4][5][6][7]. Carbon based materials such as CNT [8,9], GO [10] and graphene were also examined experimentally by a number of researcher [11][12][13][14][15][16].…”

Optimization of thermal resistance and bottom wall temperature uniformity for double-layered microchannel heat sink

“…When the heat flux reaches up to 100 W cm À2 , the conventional cooling technology is failed to meet the requirement of thermal removal as expected. Fortunately, the microchannel heat sink (MCHS) proposed by Tuckerman and Pease [1] in 1981 can endure a heat flux as high as 790 W cm À2 , which becomes a significant way for thermal management of microelectronic devices and attracts a great deal of attention [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Local convective heat transfer coefficient and friction factor of CuO/water nanofluid in a microchannel heat sink

“…Some of the previous studies showed that use of nanofluids as coolant in microchannels causes higher pressure drop in comparison with the base fluid [21][22][23][46][47][48][49][50]. Larger pressure drop occurs firstly due to larger viscosity of nanofluids compared with the base fluid (Eq.…”
