Web1.Introduction. In the past decades, researchers paid a lot of attention to simulate fluid flow. In the two-dimensional (2D) incompressible viscous fluid, the well-known Navier-Stokes equations [1], [2], [3] based on the conservation laws of mass and momentum are governing equations. It can be applied to describe the motion of liquid or gas. WebDerivation of the Navier-Stokes Equations Boundary Conditions Conservation Laws: Di erential Form Combining the di erential forms of the equations for conservation of mass and linear momentum, we have: @ˆ @t + r(ˆv) = 0 @ @t (ˆv) + r(ˆvv) = ˆb + rT To obtain the Navier-Stokes equations from these, we need to make some assumptions about our
