Linear stability, transient energy growth and the role of viscosity stratification in compressible plane Couette flow
M. Malik, J. Dey, Meheboob Alam
Linear stability and the non-modal transient energy growth in compressible plane Couette flow are investigated for two prototype mean flows: (a) the {\it uniform shear} flow with c…

Effects of Prandtl number and a new instability mode in a plane thermal plume
R. Lakkaraju, Meheboob Alam
The effect of Prandtl number on the linear stability of a plane thermal plume is analyzed under quasi-parallel approximation. At large Prandtl numbers (), we found that the…
