概要	To determine the optimum combinations among geometrical parameters of multilouvered fins, a numerical study was performed with a two-dimensional finite difference code. The code was developed by the authors using an overlaid grids method. The numerical results showed that the existence of the optimum ratio of fin-pitch/louver-pitch for each louver angle. The effects of thermal wakes on the heat transfer characteristics were discussed from the numerical results to understand the correlation between the fin geometries and heat transfer characteristics. This discussion concluded that the control of the thermal wakes after louvers was a key point for the optimization of multilouvered fins. A simple numerical expression was proposed to estimate the optimum relation among the fin parameters. The numerical expression was evaluated through the discussion about the effects of the fin parameters and performance of heat exchangers composed of multilouvered fins.
