Research Institution
This proposal entails the development of specialized CFD models which can analyze transpiration cooling processes in complex high-speed environments. This is of significant importance to the Army since “well-designed” transpiration concepts are needed on missile systems that can provide reductions in both heat transfer and skin friction, resulting in improvements in overall performance. The program of work proposed involves a systematic “building-block” approach that will support the development and validation of transpiration models for problems of increasing complexity, using both RANS and LES methodology in complex environments. The environments to be considered in our Phase I effort will be limited to gas-phase transpiration problems, but will consider the effects of combustion as well as shock interactions, and will address flowfields such as those occurring in hypersonic scramjet combustion chambers. The overall objectives will encompass: gathering building-block data sets for systematic model validation; the extension of existing RANS transpiration models to include the effects of variable Prandtl and Schmidt number; the performance of both fundamental validation studies as well as parametric studies; and, the extension of the models and methodology to an LES framework (our optional task), including the performance of a unit problem demonstration calculation.
