Sawkar, N., Modi, P., and Fingerman, M., "Numerical Investigation of Flow Induced Excitations in a Torque Converter," SAE Technical Paper 2017-01-1115, 2017, doi:10.4271/2017-01-1115.
This study analyzes the flow dynamics of a fluid within an operating torque converter. Transient computational fluid dynamics (CFD) simulations have been carried out with prescribed torque converter motions using commercially available CFD software. The analysis computes torque converter excitation forces that predict flow induced excitations during converter operation. In this study, various torque converter designs are compared and assessed with the aim of limiting flow induced excitations.
