A numerical boundary condition procedure for Euler solvers is presented. The procedure is based on a variation of the method of characteristics due to Kentzer. A second-order-accurate numerical algorithm using this procedure and the MacCormack explicit finite-difference method is presented. Results are presented for several two-dimensional and three-dimensional inviscid nozzle flowfields. Solutions obtained by the present method agree well with solutions obtained by method of characteristics algorithms and experimental data.
