### 稳态自由表面计算背后的原理

(1)

p\left( {{{\mathbf{x}}_0}} \right)-{p_{ext}} + {\mathbf{n}} \cdot {\left. {\nabla p} \right|_{{\mathbf{x}} = {{\mathbf{x}}_0}}}{\eta } = -\sigma {\nabla _s}^2{\eta }\$

Dear teacher, the free surface and the steady state free surface always show that they cannot be applied in the laminar flow horizontal concentration, and there is no way to apply them to the boundary. I do not know why, other interfaces are not occupied, because to do the free flow spreading, boundary conditions must be added. How to solve this?
