Abstract

A finite difference method with a SIMPLE algorithm was applied to numerically handle a two dimensional problem in a compact heat exchanger with louvered fins. The characteristics of physical phenomena for the fluid flow and heat transfer inside a heat exchanger are investigated by changing geometric and flow parameters such as louver angle of the fin(0), the ratio of louver pitch to fin pitch(FP/LP) and Reynolds number(Re=ULp/v). Computational results are graphically visualized and many important physical characteristics could be interpreted from those computational visualization.
