Abstract

A dynamic mesh movement algorithm and flux balancing scheme for the numerical simulation of in-depth charring ablators is developed on a control volume, cell-centered conservation equation solver with implicit gas momentum capability. Verification of the commonly employed aeroheating boundary condition is demonstrated. Modifications required to handle a time dependent computational domain are detailed in the numerical scheme and compared to a static solver. Each of the governing equations is verified against analytical solutions for both constant and linear gradient cases. Careful effort is given to elucidate implementation features required for finite volume based solvers, including strict conservatism adherence.
