Seminar High-Accuracy Computational Schemes for Realistic Unsteady Flows-FR

The fields of Large Eddy Simulation (LES) and Computational Aeroacoustics (CAA) are

focused on the accurate prediction of unsteady flow, turbulence, and noise. To

accomplish this goal, high-accuracy spatial differencing is combined with optimized

time integration schemes in order to reduce the number of grid points and time steps

required to obtain a solution. This seminar will describe the advantages and issues with the

application of these high-accuracy schemes to realistic flow problems, with emphasis on

boundary conditions, grid issues, and computational performance.

Ray Hixon graduated from the Georgia Institute of Technology in 1993 with a doctorate in Aerospace Engineering. Since then, he has been developing and applying high-accuracy Computational Aeroacoustics methods for the prediction of aircraft engine noise and performance at the NASA Glenn Research Center in Cleveland, Ohio. He is also a Professor in the Mechanical, Industrial, and Manufacturing Engineering (MIME) Department at the University of Toledo in Toledo, Ohio. He has authored 30 journal papers, 98 conference papers, and one patent.
