首先, 运动粘度 (kinematic viscosity)是一种流体的性质,property,我们可以理解为, 动力粘度 越高,该流体粘度越大,则对于 剪应力 作用下的流体形变程度越大。对于液体,动力粘度. Dynamic是“动力学的”,通常涉及“力”和“运动”,kinematic是“运动学的”,只涉及“运动”本身。 “dynamic viscosity”是动力粘度,又称为绝对粘度、剪切粘度。 “kinematic viscosity”是运动粘. 方程 (1)通常也被称为牛顿黏度定律 (针对牛顿流体),其中 \mu 也被称为动态黏度 (dynamic viscosity),我们可以把黏度系数想象成流体运动时的内部摩擦力,它起到了随着不同流层速度.
