gradient of velocity的意思|示意

Thus the difficulties of discontinuous velocity gradient and the stress singularity at the exit point are avoided, and the expense of computation is reduced.

这样回避了速度梯度间断的困难，缓和了出口处应力奇性引起的矛盾，同时又减少了计算量。

The results show that a large velocity gradient emerges in the intermeshing region of the screw reactors, which is helpful to mix materials sufficiently.

结果表明，螺杆反应器的啮合区具有较大的速度梯度，有利于物料的充分混合。

The more the bubble close to the free surface, the narrower the bottom jet develops crosswise, and the larger the pressure gradient, the rising velocity and the height of the bottom jet is upwards.

越靠近自由表面，底部射流横向发展越窄，而向上的压力梯度，气泡上升速度，底部射流上升高度越大，反之则反；

The velocity gradient, especially the perpendicular velocity gradient, leads the measuring error of flow angle with cylindrical probe to be larger than with conical multi-hole probe.

梯度使气流方向测量值向负梯度方向偏转。 圆柱探针和锥形多孔探针相比，气流方向测量误差对速度梯度更敏感，纵向梯度对俯仰角测量值的影响尤其大。

Since the gradient of the velocity is high in the mould, the control method of simulation points is applied in the least square approximation.

由于口模内速度变化梯度较大，采用最小二乘近似节点控制方法来控制近似效果。

Water potential reflects energy level of soil water and the gradient of water potential is an impotent factor describing direction and velocity of water flow.

水势反映土壤水的能态，而水势梯度则是决定水流方向和速度的重要因素。
