Heat Transfer Enhancement - an overview |

Heat transfer enhancement can have benefits beyond the heat exchanger itself, affecting the whole system of which the heat exchanger is a component. Three examples, relating to evaporation and condensation heat transfer enhancement, are given below. It will be noticed that the improvements brought about by heat transfer enhancement are the same as those attributable to compact heat …
