A Method for Eulerian Fluid Dynamics

reportActive / Technical Report | Accession Number: ADA385039 | Open PDF

Abstract:

A method is presented for obtaining numerical solutions of the Eulerian hydrodynamic equations for supersonic compressible flows. The procedure is an adaptation of the PlC method to the case of a continuous fluid. Some discussion is given concerning the limitations of the procedure the conservation of mass, energy, and momentum and the treatment of rigid obstacles and two-fluid interfaces. Examples of calculations for flows past a number of cylindrically symmetric objects are also presented.
