Investigation of shock interactions with distorted boundary layers for precision munition applications
Abstract
The objective of the proposed research effort is to develop a detailed understanding shock boundary layer interactions between a distorted boundary layer on an axisymmetric body with the shock generated by an aft protrusion. The effort will uncover the role played by the introduction of a streamwise vortex of a given magnitude into the development and evolution of a canonical boundary layer flow, determine how the shock-boundary layer interaction pressure field and the flow interactions evolve with distortion strength and shock strength, and elucidate the effects of non-zero angles of incidence on the same phenomena. The objectives will be achieved through the use of a combined experimental and computational approach. The experiments will utilize a host of advance qualitative and quantitative diagnostic techniques. The numerical effort will provide guidance for test configurations as well as interpreting and extending the experimental observations in an attempt to provide more comprehensive understanding of the underlying flow physics. Controlled boundary layer disturbances will be introduced by embedding streamwise vortices of consistent strengths at specific locations in the flowfield.
