This study explores use of Computational Fluid Dynamics (CFD) to predict near-saturated flow boiling FC-72 in microgravity. The computational method employs transient analysis detailed interfacial behavior and heat transfer characteristics along a rectangular channel heated two opposite walls. Predicted results are validated against experimental temperature measurements high-speed video images ...

Performance enhancement of the two-phase flow boiling heat transfer process in microchannels through implementation of surface micro- and nanostructures has gained substantial interest in recent years. However, the reported results range widely from a decline to improvements in performance depending on the test conditions and fluid properties, without a consensus on the physical mechanisms resp...
