Water flow boiling in a partially modified microgap with shortened micro pin fins
, 2020The flow boiling in microgap is attracting much attention due to the large potential for directly cooling the heat sources of the electronic devices, which has many advantages like high heat dissipation rate, easy fabrication, and less working fluid ...

Numerical simulations of boiling flows are discussed. The change of phase from liquid to vapor and vice-versa usually takes place in a highly unsteady manner where the phase boundary is very convoluted. Direct numerical simulations therefore require the accurate solution of the Navier-Stokes equations and the energy equation in each phase and the ...

Experimental study of flow boiling in a hybrid microchannel-microgap heat sink
International Journal of Heat and Mass Transfer, 2019A stable flow boiling operation is key to enhancing the two-phase cooling performance of microchannel heat sinks. To this end, a novel heat sink is developed which integrates a 300 μm × 600 μm straight microchannel array in the upstream region with a 25 ...

Flow boiling in microchannels and microgravity
Progress in Energy and Combustion Science, 2013Abstract A critical review of the state of the art of research on internal forced convection boiling in microchannels and in microgravity conditions is the main object of the present paper. In many industrial applications, two-phase flows are used for heavy-duty and reliable cooling and heating processes.
