On the unsteady shock wave interaction with a splitter plate: Inviscid analysis

Abstract

A planar shock wave interacting transiently with a 2D splitter plate geometry was investigated numerically over a parameter space defined by the incident shock strength (MS) and the duct height ratio (A2/A1). Eight time-accurate, inviscid simulations were performed, which provided full-field property maps and quantitative measurements of wave strengths. In particular, the flow induction characteristics of shock waves were thoroughly analyzed: quantitatively by the velocity profiles and mass flux, and qualitatively by the flow structures and conditions necessary to create flow induction. Results show that upstream flow induction does not occur for practical time scales and is strongly interrelated with the flow structures. However, the established flow conditions suggest that upstream flow induction could occur if viscous (turbulent) effects are considered. © 2013 by Nicole Renee Mendoza.
