What is the Difference Between Pool Boiling and Flow Boiling
The key difference between pool boiling and flow boiling is that pool boiling occurs in the absence of bulk fluid flow, whereas flow boiling occurs in the presence of bulk fluid flow.
Pool boiling is a heat transfer mechanism in which a phase transition occurs from liquid to vapor. Flow boiling, on the other hand, is a heat transfer mechanism that occurs when a fluid circulates over a heated surface due to external causes such as a pump or due to the natural buoyancy effect.
