Non-modal stability analysis of stratified two-phase channel flows
Ilya Barmak, Alexander Gelfgat, Amos Ullmann +1
The non-modal transient growth of perturbations in horizontal and inclined channel flows of two immiscible fluids is studied. 3D perturbations are examined in order to find the opt…

Stability of stratified two-phase flows in horizontal channels
Ilya Barmak, Alexander Gelfgat, Helena Vitoshkin +2
Linear stability of stratified two-phase flows in horizontal channels to arbitrary wavenumber disturbances is studied. The problem is reduced to Orr-Sommerfeld equations for the st…
