Abstract
In this manuscript, simulations of a canonical hollow cylinder flare using HPCMP CREATETM-AV Kestrel Component COFFE are compared to experimental data taken in the University of Tennessee Space Institute TALon Mach 4 Ludwieg tube. Preliminary comparison is with time-resolved shadowgraph image sequences of simultaneous tripped and untripped flow and unsteady pressure sensitve paint measurements. Relevant features compared between experimental and computational data are the interaction angles, wave angles, separation distance, and flow field unsteadiness. Modeling approaches are unsteady with global time stepping for modeling the untripped configuration and steady with the Spalart-Allmaras (SA) one-equation turbulence model for modeling the tripped portion of the configuration. Initial results compare well with experiment based on measurements of the angles of relevant features and qualitative comparison.
