Abstract
To accurately predict the brake performance of vehicular hydraulic retarder under oil partially filled condition, two math models were built based on different internal two-phase flow assumption. The braking torque of the hydraulic retarder was calculated using the mixture-density method or gas-hydraulic separating method. Compared with the experimental data obtained under oil fully filled condition, the calculation error is less than 5%. It is found that the separating method is more accurate in theory and the mixture method is simpler in practice.
