WebNavier–Stokes equations and boundary condition. The Navier–Stokes (NS) equations for incompressible viscous flow are (1) ∇ ⋅ u = 0, (2) ρ a = − ∇ p + μ ∇ 2 u, where ρ is the fluid density, u is the velocity and p is the hydrodynamic pressure. μ = ρ ν is the dynamic viscosity with ν being the kinematic viscosity. http://brennen.caltech.edu/fluidbook/basicfluiddynamics/potentialflow/potentialflow.pdf WebSince the (incompressible) mass continuity equation specifies the divergence of flow velocity being zero, we can replace the flow velocity with the curl of some vector ψ so that mass continuity is always satisfied: So, as long as flow velocity is represented through u = ∇ × ψ, mass continuity is unconditionally satisfied. bromake apodaca
