NUMERICAL COMPUTATION OF 3-D FLOW IN VERTICAL LAUNCHING SYSTEM
One of the most complex applications of jet plume impingement in missile launchers is the vertical launching system (VLS), where flow patterns are extremely complex and difficult to obtain numerical solutions1.The complex three-dimensional flow fields in a simplified Vertical Launching System plenum geometry are computed utilizing the Cellcentered finite-volume code. 3rd-order upwind spatial differencing with TVD option for shock capturing is applied for three-dimensional Navier-Stokes governing equations, with q-ω two-equation turbulence model. Dual time stepping and preconditioning procedure are applied for improving the calculating convergence velocity. The diagonalized, dual-time ADI algorithm is employed to integrate the governing equations. Shock forming in the plenum chamber is simulated accurately. The complex flow pattern in Vertical Launching System was described veritably.
