Binstock, J

A difference equation technique suitable for clean, dynamic mix, and turbulence Lagrangian calculations is shown. This new technique is compared to the standard one for clean one-dimensional calculations of the Noh, Sedov Blast Wave, and Strong Shock Tube test problems, and for a one-dimensional two-phase flow dynamic mix calculation of a modified Noh problem, all test problems involving shocks. The new technique is shown to dramatically reduce the noise in the calculated hydrodynamic quantities of pressure, density, specific internal energy, and Lagrangian interface velocity.
