    Abstract

    A vertex based Euler code, JUEL3D has been employed to compute supersonic flow past a multi-body launch vehicle. The code is multi-block structured and capable of handling any arbitrary three dimensional single/multi-body geometry. The algorithm is based on vertex based finite volume space discretisation with five stage Runge-Kutta time stepping scheme to advance the solution in time.13; Enthalpy damping, implicit residual averaging, local time stepping and grid sequencing are used to accelerate the convergence to steady state.13; The computations have been carried out on a stacked H type grid for13; III,, - 2.09 and a = 0 xB0;and 4 xB0; and the results are compared with13; experiments. Details of the Eider solver, and the grid generation codes13; are also explained in this report along with sample input/outout to13; introduce the code to general users.
