Simulation of Reacting Flows

These researchers are continuing their numerical simulations of high-temperature reacting flows. This work has several applications: supersonic flow control using laser energy deposition, simulation of planetary entry capsules, design and optimization of hypersonic inlets, and modeling and simulation of injection and mixing in supersonic cross-flows. For this work, the researchers use their newly developed unstructured grid computational fluid dynamics code. This code uses implicit time integration to reduce the computational cost, and has been optimized for distributed memory parallel computers. The group is studying several critical problems in the area of hypersonic aerodynamics, including turbulent mixing in base flows and modeling of turbulent fuel-air mixing. In addition, they are developing improved grid partitioning schemes to improve the performance of the code. This work is leading to an improved understanding of how chemical reactions and fluid motion interact in a variety of technologically relevant applications.
