In this study, the ventilation of duct is simulated by CFD and thermal changes on the seat surface are measured experimentally. These models are the improved duct and the existing one installed at the real seat in order to test the thermal change 1 minute later. The seat with the existing duct has the temperatures of 26℃ and 25℃ on lumber and femoral parts respectively. However, the seat with the improved duct has the temperature of 1℃ lower than the seat with the existing duct. This result contributes to develop the improved duct. Hereafter, the methods used in this study are expected to be useful at checking the flow resistance loss of the ventilation seat duct and assessing the flow channel design.
