Stability of stratified two-phase flows in inclined channels
Ilya Barmak, Alexander Gelfgat, Amos Ullmann +1
Linear stability of stratified gas-liquid and liquid-liquid plane-parallel flows in inclined channels is studied with respect to all wavenumber perturbations. The main objective is…

On acceleration of Krylov-subspace-based Newton and Arnoldi iterations for incompressible CFD: replacing time steppers and generation of initial guess
Alexander Gelfgat
We propose two techniques aimed at improving the convergence rate of steady state and eigenvalue solvers preconditioned by the inverse Stokes operator and realized via time-steppin…

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…
