NOVEL ACCESSORY FOR URINARY LEG BAGS

Not Available This project addresses the specialization and upgrade of unstructured CFD numerics for the simulation of missile aerodynamic flowfields with lateral/divert jet interactions. Starting unstructured capabilities are advanced and include gas-phase chemical kinetics and two-equation turbulence modeling in an upwind/implicit (Roe-TVD/GMRES] framework that operates in a parallel environment (domain decomposition/MPI) and includes multiple elements (sets, hexes, prisms, etc.). Principal Phase I upgrades will include solution adaptive gridding using extension of the 3DTAG/3DMAG embedding methodology of Biswas and Strawn, and, the recent jet adaptation work of Baker. Other upgrades will include explicit algebraic stress model (EASM) turbulence extensions with compressibility corrections, coupling of k into the energy balance, and the performance of checkout studies. Detailed comparisons with fundamental lateral jet flow data will be performed and methodology for inclusion of turbulent/particle and turbulent/combustion interactions will be formulated. An optional task entails the detailed multiprocessor unstructured analysis of an AIT missile divert jet interaction flowfield with the advanced turbulence framework utilizing Let based and hex based grids with several levels of solution adaptive refinement. BENEFITS: The proposed research paves the pate for utilizing unstructured numerics to solve advanced missile system aerodynamic flows in a much more accurate and efficient mann
