Leakage Area

To understand the effect of internal leakage on the torque field and characteristics of a torque converter (TC), a transient analysis was performed on the internal flow of a TC and the pressure pulsation characteristics of monitoring points in the convection channel. It was found that dividing the leakage area of the TC into a separate watershed improved simulation accuracy by 4%. When there was a leakage area, there were distinct collision, mixing, and assimilation stages between the leakage flow and the main flow. These phenomena caused energy loss that was highest at low speed ratios. However, the leakage flow always accounted for 12% of the main flow regardless of the speed ratio. At the same time, the leakage flow had a larger influence on pressure pulsation inside the TC and especially the low frequency band was more substantial. This shows that the leakage area has a large influence on the TC performance, energy loss, and flow state. Analysis of the leakage area showed that reducing the leakage area helps to improve powertrain performance and fuel economy.

Distribution Of Flow

According to the issue of CVT torque converter internal flow field such as the complexity and not easy to calculate, the channel model of torque converter is established by UG, the grid of channel model is generated by GAMBIT, the internal flow field of torque converter is simulated based on FLUENT while the pressure and velocity distribution of flow field are calculated under three different conditions. The results show that analyzing the flow field of torque converter by FLUENT has certain guiding significance for the design and optimization of torque converter.

Hot Film Anemometry

Unsteady flow measurements were performed to investigate the internal flow field of a torque converter, especially unsteady rotor/rotor-interaction in the region between pump exit and turbine inlet. Instantaneous flow data were measured with hot-film probes and a computer based data acquisition system. The commonly used ensemble averaging method was adapted to this special case with two independently rotating impellers. Velocity profiles of the flow in the relative frame of reference of the pump impeller were evaluated and they were used to generate a computer animation. The paper gives an overview over the test facilities and the background of the present investigations. It follows a discussion of some essential aspects concerning the use of hot-film anemometry. The methods used to evaluate the data are described in detail and measuring results of the region between pump exit and turbine inlet are presented.
