However, the excessive consumption of liquid-phase by highly localized heat source causes the two-phase flow maldistribution, leading to a significantly reduced heat transfer coefficient, high-pressure loss, and limited flow rate. In this study, flow...

... and the liquid enters the microgap at 18 °C. When the heat flux reached 79 W/cm 2 , two-phase flow was observed around the last columns of pin fins in the microgap in slug flow regime. The slug regime developed in the microgap upon increasing the heat flux to higher values such as 207 W/cm 2 (Fig. 8...
