Abstract

Secondary small-scale Kelvin-Helmholtz instability, developing along the Mach reflection slip-stream, was investigated. This instability is the cause for thickening the slipstream. Growth rates of the large-scale Kelvin-Helmholtz shear flow instability are used to model the evolution of the slip-stream instability in ideal gas. The model is validated through experiments measuring the instability growth rates for a range of Mach numbers and reflecting wedge angles. Good agreement is found for Reynolds numbers of Re > 2 × 104 This work demonstrates, for the first time, the use of large-scale models of the Kelvin-Helmholtz instability in modeling secondary turbulent mixing in hydrodynamic flows, a methodology which could be further implemented in many important secondary mixing processes
