WebThe momentum equation is given both in terms of shear stress, and in the simpli ed form valid for incompressible Newtonian uids with uniform viscosity. Vector Form These are the equations written using compact vector notation. The continuity equation (conservation of mass): Dˆ Dt + ˆr~u= 0 (1) The motion equation (conservation of momentum ... WebThe vorticity equation can be derived from the Navier–Stokes equation for the conservation of angular momentum. In the absence of any concentrated torques and line forces, one obtains: Now, vorticity is defined as the curl of the flow velocity vector; taking the curl of momentum equation yields the desired equation. panwin designs ltd
