In this section we have derived the famous Navier-Stokes equation which is the equation for the conservation of momentum. As this equation is a vector equation, it will give rise to a total of three equations that we require for solving the field variables. We have derived the Navier-Stokes...

为什么纳维-斯托克斯方程(Navier-Stokes equation)只适用于不可压缩实际流体?不适用于可压缩方程吗? 方程里面也有密度符号。若为理想流体,则方程就化为欧拉运动方程式。但欧拉运动方程式是可压缩不可压缩的流体都适用的。 但为什么 N…NS 和 Euler 均有可压缩和不可压缩的形式。牛顿流体粘性切应力与应变成线性...
