SHOCKS

In the present SciDAC Science Application, we propose to develop a new capability based on high-order high-resolution schemes to simulate shock-turbulence interactions and multi-material mixing in planar and spherical geometrical configurations and study the turbulent RT and RM mixing. These problems are of relevance to ICF capsule implosion and supernovae explosions. The project also involves the development of novel sub-grid models for shock-turbulence interaction and multi-material mixing and its validation using the DNS data. The computational code development involves a sequence of benchmark problems to test the ability of the proposed computational algorithms and their implemented performance. Ensuring good scaling performance on massively-parallel computer architectures and developing systematic methods for quantifying uncertainty in nonlinear simulations of turbulent flows are other important parts of the proposed program... We have identified specific algorithms which require..
