Improvement of prediction accuracy for torque converter performance: One-dimensional flow theory reflecting the stator blade geometry

Specific fuel consumption is a key word these days, and the torque converter can play an important role in improving it. This makes it essential to improve the accuracy of methods for predicting torque converter performance. In this work, the accuracy of performance predictions ws improved by replacing the flow angle and total pressure loss in the angular momentum theory with corresponding values obtained by analyzing the flow around the stator using a general flow analysis code. A quick and highly accurate prediction of torque converter performance is made possible with this method.
