Noack, R W; Lopez, A R

This is the first of two volumes concerning the SANDia Inviscid Afterbody Code. The SANDIAC computer code predicts the supersonic and hypersonic inviscid flow field about reentry vehicles. The theory, formulation, and results of the code are described in Volume I, and the inputs and usage are described in Volume II. The code solves the three-dimensional, steady-state, Euler equations in finite difference form. The equations are solved in a transformed computational plane. A parabolic grid generation scheme is used to provide body normal grids for complex configurations. The code has options to solve the conservative and nonconservative Euler equations using either upwind differencing or standard centered differencing. The calculations may use either equilibrium or ideal gas chemistry. The code provides the complete flow field in addition to integrated force and moment data as output. 42 refs., 47 figs.
