ON CERTAIN FINITE DIFFERENCE SCHEMES FOR THE EQUATIONS OF HYDRODYNAMICS
Technical Report
·
OSTI ID:4726670
The application of two finite difference schemes of second order accuracy to the equations of viscid and inviscid flow is examined. The first is the Lax-Wendroff scheme, the second an iterative scheme. A stability criterion is obtained for the iterative scheme by the method of von Neumann, and an empirical stabtlity criterion is obtained for the Lax-Wendroff scheme as applied to viscid flow. The accuracy of these methods and their effectiveness for tlows that contain a shock are also discussed. (auth)
