Abstract

"Development of an unstructured-grid based PNS/NS CFD solver provides advances in unstructured-grid technology to provide a more efficient analysis tool. Over a wide range of the missile flight trajectories, a PNS methodology is sufficient and a more costeffective approach to provide CFD analysis capability than a traditional NS approach. Overall memory and the CPU requirement can be reduced to provide a predictive CFD capability running on modern desktop platforms. With the latest announcement by IntelCorporation to provide 64-bit PC architecture, traditional expensive hardware requirements could be replaced with a more cost-effective class of PC desktops.The technical challenge is to merge the grid generation process with a hybrid PNS/NS CFD solver. The goal of this SBIR effort is to develop necessary techniques required in integrating grid generation and the data structure topology to the flow solver.Under a Phase I effort, a hybrid PNS/NS solver will be developed from an existing NS solver, and a 2D grid generator will be integrated into the flow solver. With a continuation of Phase II effort, the method developed will be extended to a 3D flowsolver. With the software developed in object-oriented approach, other physical models such as chemically reacting flows, turbulent flows, multi-phase flows could all be added as a module to the developed baseline capability. The method and the resulting software as proposed by this effor
