Abstract
The work presents the results of numerical modeling of
a supersonic flow around a blunted cone with an isolated cylindrical roughness on
the forebody surface in the three-dimensional formulation.
The roughness element is shown to
distort the mean flow and to give rise to small-amplitude disturbances
with distinguished spectral peaks in the boundary layer.
