5. Global energy analysis
Comparing one exchanger to another depends on the type of performance expected (maximum heat transfer, minimum investment cost, operating cost, weight, volume, mechanical power required, resistance to extreme conditions, service life, etc.). In addition, the process in which the exchanger is included cannot be ignored, and optimization must take this into account . Here, we limit ourselves to a comparison of the thermal power transferred and the mechanical power required for fluid circulation.
In fact, an exchanger whose flow transferred (thermal power) is Φ, requires mechanical power Φ meca to ensure...
