A third-order-accurate compact upwind differencing scheme designated 'CUD-3', which has been developed for the approximation of connective terms, is presently applied in different forms of hydrodynamic equations. Its 'CUD-5' extention is also presented. It is shown that there is no limitation on cell Reynolds number with CUD-3. Illustrative applications of the method are in the computation of vorticity isolines at successive moments in a Prandtl vortex-pair problem, and in the unsteady viscous flow about a circular cylinder.
