The separation flow is three dimensional in hydraulic machine. The pressuregradient in cross direction produces secondary flow in boundary layer.
水力机械的分离为三维流动,三维流动的侧向压力梯度产生边界层的二次流动。

The pressuregradient of the anti-lock braking system (ABS) was experimentally studied using an ABS hydraulic test bench for various conditions including normal brake, on-off brake, and step brake.
Second, the state of inter-aggregate pore water of cohesive soil is determined by(balanced) condition between damping of bound water membrane and permeability pressure of hydraulicgradient.
