因此符合广义牛顿粘性假设的流体即可适用Navier-Stokes方程。2.由题主的疑问，大胆猜测题主学的是工程流体力学一类的课程，其中使用的Navier-Stokes方程已经按照不可压缩假设{\rm div} \overrightarrow{V}\equiv 0 删去了散度项（或者从一开始就没有考虑过），然后取运动学摩擦系数\nu=\frac{\mu}{\rho} 得到的...

Navier-Stokes equationmetallurgycastingIn considering the Navier-Stokes equation, the forces on the faces of an elementary cubic volume in a liquid or gas are analyzed. That provides a clear physicomechanical interpretation of individual terms within the equation. As a result, the Navier-Stokes ...
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...

Equations [1] and [2] also include terms to describe the Coriolis acceleration: fu or fv. The Coriolis terms represent the effect of the Earth’s rotation on the ocean, which appears like a ‘force’ in the equation, but is only an effect of viewing the oceans from a reference frame ...
