Dominique Hoskin is a PhD candidate investigating transitional hypersonic boundary layers and shockwave boundary layer interactions, with a specific focus on boundary layer receptivity to freestream disturbances. A key objective of his work is discovering the sensitivity of hypersonic boundary layer simulations to computational grid resolution in the leading-edge region. As a MathWorks Fellow, Dominique will focus on using the EXASIM code, a massively parallel high- order discontinuous Galerkin finite element code, to perform direct numerical simulations in three dimensions on a hypersonic flat plate with and without an impinging shockwave. To accomplish these objectives, he has been given an allocation of node hours on the SUMMIT supercomputer at the US Department of Energy’s Oak Ridge National Laboratory. The anticipated results of his work could greatly improve the understanding and management of boundary layer transition on hypersonic vehicles, which is essential to vehicle design and performance. More broadly, his work could have significant implications for the performance of high-speed vehicles.
