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...

在求解不可压缩流体问题时，利用Navier-Stokes方程描述流场，通过PINN方法可以实现对流场参数的求解。实验结果显示，PINN能够准确预测流场中的速度分量u和v以及压力p，验证了其在复杂流体动力学问题求解方面的有效性和实用性。通过训练和优化，PINN不仅能够解决正问题，还能处理逆问题，为物理系统建模和参数识别...

The Navier-Stokes equation of two-dimensional neutral fluid turbulence is similar to three-dimensional case, except that ∇ should be replaced by ∇⊥ with the anisotropy assumption kz≪k⊥ . Therefore, quantities like the velocity v and the vorticity Ω=∇⊥×v are functions of (x,y)...
