Shock wave turbulent boundary layer interaction over a protrusion
Abstract
This research attempts to investigate an important and common phenomenon in
aerodynamics called shock interaction in a turbulent flow’s boundary layer. Due to advancements
in current computational units, more complex geometries could be simulated with providing
more accurate results. The tools used in this investigation are computational turbulent model of
hybrid RANS/LES, called detached eddy simulation (DES). DES and its variant delayed
detached eddy simulation (DDES) were the two computational schemes used for numerical
simulation. Two protrusions were focused on in this work: a symmetrical bump and a proposed
aircraft UHF antenna. Computation where performed with commercial software Cobalt and
FLUENT in the High Performance Computing Center (HiPeCC) in Wichita State University.
Computational simulation is costly in terms of energy consumption and time usage. Even so with
the advanced computational units of HiPeCC, using in average of 18 processors, total simulation
for this research took over 2 months of simulation.
