Abstract
A vertex based Euler code, JUEL3D, has been employed to compute inviscid flow past the GSLV configuration, consisting of a core vehicle with four scrap-onboosters. The algorithm uses finite volume space discretization with a five stage Runge-Kutta time stepping scheme. Enthalpy damping, implicit residual smoothing, local time stepping and grid sequencing can be used to accelerate the convergence to steady state. The code is multi-block structured and can handle any arbitrary single/multi-body geometry. Computations have been carried out on two stacked O-H type grids. The sectional two-dimensional grids, using a single block and a two block strategy are generated by the solution of elliptic equations. The simulation of the geometry and the grid generation procedure are described in detail. Computed results for transonic and supersonic test cases are compared with available experimental data.13;
