Numerical prediction of the thermo-hydraulic performance of secondary surfaces for compact heat exchangers

This work presents a numerical analysis of the thermo-hydraulic performance of secondary surfaces for compact heat exchangers of the plate and fin type. The study resulted in the determination of the film heat transfer coefficient and its variation with the distance from the exchanger inlet. The numerical results obtained provide a thorough description of the performance of the flow inside the exchanger and the heat transfer coefficient shows a similar behaviour compared with analytical models.
