Development of TDOS (Torque converter Design Optimization System), an integrated design process, is presented. The main functional groups of TDOS are torque converter geometry designer, 3D CFD analysis module, and design optimizer. For the geometry design, an in-house code BPG (Blade Profile Generator), is employed to create the 2D torus and 3D blade coordinates with given design constraints. To obtain an accurate performance results, an automated CFD analysis module is created which includes 3D geometry modeling, mesh generation, solving and result analysis. All CFD parameters that affect the accuracy of solution such as mesh size, simulation scheme and boundary conditions are predefined for the automated CFD analysis. The optimal parameters for CFD analysis are determined from the previous study of mass-produced torque converters. Having automated the geometry design and CFD analysis process, an optimization procedure of torque converter geometry is developed.
