On direct inverse of Stokes, Helmholtz and Laplacian operators in view of time-stepper-based Newton and Arnoldi solvers in incompressible CFD
H. Vitoshkin, A . Gelfgat
Factorization of the incompressible Stokes operator linking pressure and velocity is revisited. The main purpose is to use the inverse of the Stokes operator with a large time step…

Destabilization of free convection by weak rotation
Alexander Gelfgat
This study offers an explanation of a recently observed effect of destabilization of free convective flows by weak rotation. After studying several models where flows are driven by…

Experimental observation of the steady - oscillatory transition in a cubic lid-driven cavity
A. Liberzon, Y. Feldman, A. Yu. Gelfgat
Particle image velocimetry is applied to the lid-driven flow in a cube to validate the numerical prediction of steady - oscillatory transition at lower than ever observed Reynolds…
