Abstract:

A new three-dimensional nonequilibrium diagonal approximate Newtons algorithm NEDANA has been developed for flows with thermal and chemical nonequilibrium. Changing chemistry and thermal models is straightforward because the flow solver receives chemical, thermodynamic, and transport properties from the NEQPAK library of subroutines. The flow solver is developed in the chimera domain decomposition architecture in order to incorporate complex multiple-body configurations and moving grids. Excellent agreement was obtained in comparisons of the new flow solver with steady-state experimental data and solutions from existing state-of-the-art flow solvers.
