The aim of this investigation was to develop computer-aided performance prediction and design procedures for all types of hydrokinetic transmission units. The types of fluid transmissions considered were Fluid Couplings, Three Element Torque Converters and Multi-Element Torque Converters. Two types of analyses were used to investigate these units. The Forced Vortex Theory and The Single Mean Streamline Theory. In both cases the energy dissipated in the flow path was considered to be composed of incidence or shock losses, friction losses and secondary circulation or bend losses. Initially, the Single Mean Streamline Theory was developed for the design of Fluid Couplings and Three Element Torque Converters. The procedure was assessed by comparisons with existing designs and then developed into a generalised computer program procedure for the design of Multi-Element Torque Converters. A computer procedure for the performance prediction of Multi-Element Torque Converters was developed in a similar way. To supplement the theoretical work, a rig to visualise flow behaviour inside a Three Element Torque Converter was built.
