概要 To determine the optimum geometries of louvered fins, a parametric study on fin pitch, louver angle and fin thickness was performed with a two-dimensional finite difference code developed by the authors using an overlaid grids method. The numerical results showed the existense of the most effective ratio of fin-pitch/louver-pitch for each louver angle, which controls the thermal wakes formed after louvers. From the discussion about the effect of thermal wakes, a numerical expression that estimated this optimum relation among the fin parameters was proposed. The estimation of the performance of heat exchangers consisted of these optimized louver fins showed that a heat exchanger with smaller louver angle(θ) had superior performance in the range of 20°≤θ≤30°.
