2424 トルクコンバータ・ステータの大流入角特性(S41-4 流体機械に関連した複雑内部流動の解析と計測(トルクコンバータ・水車・ポンプ),S41 流体機械に関連した複雑内部流動の解析と計測)  [in Japanese] 2424 High Inlet Flow Angle Characteristics of Torque Converter Stator  [in Japanese]

Flows around the stator of a torque converter for automobiles were investigated using a general purpose CFD code. The complicated separated flows in the lower speed ratio range were computed with the k-ε model and some other deviation models. The flow measurement using PIV system was also conducted in order to evaluate the accuracy of the computed results. The results showed the low Reynolds number type second-order non-linear k-ε model gave the closest result to the measured results. The standard k-ε model was not suited for such a complicated flow as the case. The results also confirmed that the exit flow angle decreased as the inlet flow angle excessively increased.
