Modeling of pressure drop and heat transfer for flow boiling in a mini/micro-channel of rectangular cross-section
TL;DR: In this paper, a one-dimensional model is proposed to estimate the pressure drop and heat transfer coefficient for flow boiling in a rectangular microchannel, taking into account the pressure fluctuations caused due to the confined bubble growth and the effect of pressure fluctuations on the heat transfer characteristics.
