二次调节液压混合动力车辆通过保证发动机工作于高效区以及回收和再利用制动能来提高车辆的燃油经济性。相对于电动技术,二次调节静液传动技术具有功率密度大和全充全放能力强的优点,但是较低的能量密度需要功率匹配和特殊控制策略来实现动力元件的最优工作方式。提出多目标优化方法识别液压混合动力车辆关键元件参数的最优解位置,设计液压再生制动策略和能量利用策略来回收和再利用车辆的制动动能。研究结果表明,关键元件的参数匹配和提出的控制策略能有效地提高车辆在城市工况下的系统效率和燃油经济性。

The aim of the paper is to present the results of investigations conducted on the free surface flow in a Pelton turbine model bucket. Unsteady numerical simulations, based on the two-phase homogeneous model, are performed together with wall pressure measurements and flow visualizations. The results obtained allow defining five distinct zones in the bucket from the flow patterns and the pressure signal shapes. The flow patterns in the buckets are analyzed from the results. An investigation of the momentum transfer between the water particles and the bucket is performed, showing the regions of the bucket surface that contribute the most to the torque. The study is also conducted for the backside of the bucket, evidencing a probable Coanda interaction between the bucket cutout area and the water jet.
