Research Topic Description, including Problem Statement:
Problem statement: Current approaches for computational fluid dynamics (CFD) simulations of fast moving objects under high temperatures and high stresses are physics-limited and computationally intensive.
Topic Description: Modern aerodynamic CFD codes do not perform well under extreme conditions (i.e. high temperatures, high-stress forces, turbulence, ablation, etc.), are too computationally intensive to conduct iterative simulations and require too much manual time to create sophisticated grids. Improved CFD techniques that incorporate relevant physics effects are desired for high-fidelity modeling of fast moving objects. In addition, modern techniques and datasets need to be developed for verification and validation of simulations.
Improve CFD predictions under extreme conditions by developing methods and incorporating effects such as: turbulence, boundary layer transitions, high temperature, shock/boundary layer interactions, ablation, and structural interactions. One approach could be to add these physics effects to current CFD tools and compare with observations. Another approach could be to implement a systematic grid refinement around areas that need higher-fidelity to observe aerodynamic structures vs. areas that do not. Last, develop techniques and capabilities that enable assisted or automated grid generation for axis-symmetric systems. One approach for this could be the development of scripting that is based on a library of grid generation modules, specific for axis-symmetric objects.
Relevance to the Intelligence Community:
Improved ability to CFD model under extreme conditions will enhance the Intelligence Community’s ability to characterize fast moving objects.
