Fluid Flow and Heat Transfer Characteristics in Multi-Louvered Fin Heat Exchanger

The two-dimensional conservation equations of mass, momentum and energy are solved numerically in order to investigate the thermo-fluid phenomena in the louvered fin array. The governing equations are expressed in the generalized coordinates to consider the complex geometry of louvered fin array. The numerical solutions give the detail distribution of velocity and temperature fields from the inlet to the outlet in the louvered fin array. The pressure drop, flow efficiency and heat transfer rate are calculated as a function of Reynolds number in order to know the optimal design condition with larger heat transfer rate under smaller pressure drop.
