Recent Advances on Pool Boiling Heat Transfer Processes

Pool boiling is one of the efficient ways to remove heat from high-power electronics, heat exchangers, and nuclear reactors. Nowadays, the pool boiling method is tried to exercise frequently due to its ability to remove high heat flux compared with natural/forced convection, while maintaining at low wall superheat. But this pool boiling heat transfer capacity is also limited by an important parameter, called critical heat flux (CHF). At the point of CHF, the heat transfer coefficient (HTC) drastically decreases due to the change of the heat transfer regime from nucleate boiling to film boiling. This is why, the enhancement of CHF, while maintaining low wall superheat is of great interest to engineers and researchers.
