Abstract:

A calculation method for the braking torque of the hydrodynamic retarder under partial filling condition was proposed based on the one-dimensional flow beam theory to estimate the retarder braking performance in the product design phase. The proposed method as well as the general CFD numerical simulation were applied to calculate the braking performance of D300 type hydrodynamic retarder under partial filling condition and the results were compared each other. The both results show a good agreement, proving the effectiveness of the proposed method.

Key words: fluid transmission and control, hydrodynamic retarder, one-dimensional flow beam theory, braking torque
