Abstract
In this study, we verify the accurate numerical analysis and simplify the perforated plate of inlet and exhaust duct using porous media for the cost reduction and the efficiency improvement of thermal-fluid analysis to evaluate cooling performance of wheel-loader. The flow loss coefficient of the perforated plate is defined by the experiment result. To define analytically the flow loss coefficient of the perforated plate, we calculate the pressure drop of unit-cell and compare to experiment result. Finally, we compare the heat balance test and the simplified simulation result on the inlet and exhaust duct of wheel-loader. After this study, we verify the applicability of the simplified analysis method on the inlet and exhaust duct of wheel-loader. And, foundation which can carry out effectively the evaluation and improvement for cooling performance of wheel-loader is prepared.
