- Abstract
- Keeping pace with the current rapid development of clean energy, hybrid cars and electric vehicles are receiving extensive attention. Inelectronic control brake systems, which are essential to these vehicles, a solenoid valve is used to control the hydraulic pressure, whichboosts the driver’s braking force. However, strong cavitation occurs at the narrow gap between the ball and seat of a solenoid valve dueto sudden decreases in pressure, leading to severe damage to the valve. In this study, we numerically investigate cavitation in a solenoidvalve to discover geometric parameters that affect cavitation, and we develop an optimal design to minimize the cavitation using an optimizationtechnique. As a result, we propose two design guides for the solenoid valve subject to cavitation: the ratio of the narrowest gaparea to the inlet area and the narrow gap length. We also find that preventing a sudden reduction of a flow passage is important to reducingcavitation. Finally, using an evolutionary algorithm for optimization we minimize cavitation. The optimal design results in a maximumvapor volume fraction of 0.051, compared to 0.74 for the reference model.
