Abstract

The research of performance of louvered-fin Compact Heat Exchanger is done by simulating the problem using Ansys CFX Software. This report will represent the result from the simulation done by CFX Software along with the discussion and conclusion. The fluid used in the simulation is air at 25°C and the speed of the air enter through the inlet is 15m/s. At the end of this study the optimum geometry that is suitable for mass use will be discussed. This study have found that the optimum geometry to enhance the heat transfer performance for louvered fin compact heat exchanger is 29° louver angle and 1.30mm louver pitch. The results of the optimum geometry of the louvered fin have been validated by study done by previous academician. The performance of this louvered fin type compact heat exchanger has been evaluated by monitoring the temperature drop at the fin by the observing of the temperature contour. The conclusion of this study is that the louvered fin will enhance the heat transfer performance because of the increasing in the heat transfer surface area. And when the air is flowing through the louvered fin array, the flow is louver directed pattern and will cause great temperature drop at the fin plat. Louver directed flow and axial directed flow will be the main reason in enhancing the heat transfer performance of the louvered fin compact heat exchanger.
