纳维-斯托克斯方程是一组非线性的 偏微分 equations describing the motion of viscous fluid substances. They are a statement of Newton’s 第二定律, balancing momentum changes with 压力 梯度、粘性力和外力。对于不可压缩流体,方程为 [latex]\rho (\frac\{partial \mathbf{v}}\{partial t} + \mathbf{v} \cdot \nabla \mathbf{v}) = -\nabla p + \mu \nabla^2 \mathbf{v} + \mathbf{f}[/latex]。.
