A set of experimental platforms with widths 0.5, 1.0, 1.5, and 2.0 mm was established to explore the mechanism flow boiling bubble dynamics in microchannels, focusing on heat transfer characteristics, pressure loss, two-phase pattern identification. Bubble flow, restricted dry area were observed all four channels. The appearance related rate channel width. Under condition same width, initial fl...

basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. an efficient approach to studying cooling system for diesel engine is a 3d computational fluid dynami...

Subcooled liquid boiling makes it possible to remove extremely high heat flux densities (tens, and under certain conditions even hundreds of MW/m2). This method is used for cooling rocket nozzles, in metallurgy, thermonuclear power special installations (cooling beam targets), pulsed magnetohydrodynamic (MHD) installations. However, the calculations this process are based on purely empirical co...

In the present study, three-dimensional numerical simulations are performed to examine effect of applied direct current electric fields on subcooled flow boiling heat transfer in a vertical minichannel. The volume fluid model is used capture liquid–vapor interfaces, and conservation laws, together with electrohydrodynamic (EHD) equations, solved using finite method. Two mass models Lee Fourier ...
