Instabilities in stratified mixing layers

Gelfgat & Kit, JFM, 2006, vol. 552, pp. 189-227


Compare temporal and spatial perturbations for isothermal flow:

 

 inviscid fluid:    l=0.1    l=0.5    l=0.9     l=1

 

 viscous fluid, Re=100:    l=0.25    l=0.5     l=1

 

 

Compare temporal and spatial perturbations for non-isothermal flow:

 

 inviscid fluid, small x:    l=0.25    l=0.5

 inviscid fluid, large  x:    l=0.25    l=0.5

 viscous fluid, Re=100:   l=0.25    l=0.5

 

 

Compare profiles of the Kelvin-Helmholz and Homboe perturbations
