    Abstract

    The Background Oriented Schlieren technique has been applied to determine the density field in an oblique shock-separated turbulent boundary flow. Measurements were made for two cases, namely, with/without jet flow at flow at the base. Both instantaneous and time averaged density field have been obtained – these results show certain upstream features of interest including shock excursions. The mean density field is discussed along with conventional Schlieren flow visualization. The study involving shock boundary interaction, movement of freestream shock over the afterbody in the presence of a jet plume provides understanding of flow physics in a flow regime where whole field velocity measurements are extremely difficult.
