Abstract：In order to design hydrodynamic torque converter with high perfomance and improve efficiency by internal flow law to better analyze the internal flow, organic glass was used to prepare the model of hydraulic torque converter. The transparency was improved by the model to achieve visualization of internal flow field in pump. Particle image velocimtry (PIV) was used to measure the internal flow field at different working conditions with the braking condition of i=0 , the traction of i=i* and the noload condition of i=1.The radial and axial flow images were acquired and analyzed qualitatively. The results show that the velocity and direction of tracer particles on behalf of fluid flow can be seen clearly from the collected images. It is feasible to test the internal flow field of the pump by PIV.
