Towards a better hydro for dynamic mix calculations
Abstract
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.
