Comparative Study of Thermal Performance of Liquid Metal and Water Flow Through a Channel

Abstract

The heat transfer performance of a liquid metal flowing inside a 1-mm channel with different lengths was numerically investigated and compared with water. Inlet velocity of the liquid metal was varied to simulate same inlet velocity and pressure drop conditions as water. Pressure drop and heat transfer coefficient for both fluids were compared for different channel lengths and wall heat flux. It was found that the performance of the fluids is influenced by the heat flux, but is strongly dependent on the channel length-to-diameter ratio and the inlet flow rate used.

A review on heat transfer and hydrodynamic characteristics of nano/microencapsulated phase change slurry (N/MPCS) in mini/microchannel heat sinks

“…In order to further enhance the cooling ability of the currently available mini/microchannel heat sinks, researchers have investigated the cooling system configuration [3,4,5], working fluids [6,7,8] and other relevant parameters [9][10][11][12]. Among these methods, the mini/microchannel heat sink with N/MPCS as working fluid has attracted the researchers' attentions, because it combines the advantages of both mini/microchannel and N/MPCS.…”
