.... The last few decades have witnessed the development of several drag torque models for wet clutches. Kitabayashi et al. [ 4 ] presented a theoretical model based on laminar flow in the gap between the disks. However, the model assumes a full ATF film at all the speeds; hence it is suitable for predicting...
