Mitigation of Optical Distortions in a Free Shear Layer Using Feedback Flow Control

  title={Mitigation of Optical Distortions in a Free Shear Layer Using Feedback Flow Control},
  author={Jurgen Seidel and Casey Fagley and Robert B. Decker},
  journal={2010 DoD High Performance Computing Modernization Program Users Group Conference},
The development of a flow-state database, including the optical aberrations caused by density variations, of the separated shear layer behind a backward-facing step is discussed in this paper. Delayed Detached-Eddy Simulations (DDES) using Cobalt are performed to investigate the flow field, both in its natural, unforced state and when periodic forcing is applied. The results indicate that the large, coherent structures in the shear layer cause the most severe optical aberrations, while the… CONTINUE READING
