A multidimensional implicit Navier-Stokes analysis which uses numerical solution of ensemble averaged Navier-Stokes equations in a nonorthogonal, body-fitted, cylindrical-polar coordinate system has been applied to simulation of the Internal flow field in solid propellant rocket motor chambers with segment joints. The calculation procedure incorporates a two-equation (k-epsilon) turbulence model and utilizes a consistently split, linearized block implicit algorithm for numerical solution of the governing equations. Computations performed to simulate the axisymmetric flow field in the vicinity of the aft field joint in the space shuttle solid rocket booster using 14.725 grid points show the presence of a region of reversed axial flow near the downstream edge of theslot. Calculations were also performed for two cases involving asymmetric three-dimensional flow in the vicinity of the aft field joint in the SRB using 721.525 grid points to estimate circumferential velocities and pressure gradients at the joint.
