Instability of stratified air-water flows in circular pipes
Ilya Barmak, Alexander Gelfgat, Neima Brauner
This work deals with stability of two-phase stratified air-water flows in horizontal circular pipes. For this purpose, we performed a linear stability analysis, which considers all…
Generation of interfacial waves by rotating magnetic fields
Gerrit Maik Horstmann, Yakov Nezihovski, Thomas Gundrum +1
Interfacial waves arising in a two-phase swirling flow driven by a low-frequency rotating magnetic field (RMF) are studied. At low RMF frequencies, of the order of 1-10 Hz, the osc…
Flow of a shear-thinning fluid in a rectangular duct
Ilya Barmak, Davide Picchi, Alexander Gelfgat +1
We address the problem of steady laminar flow of a shear-thinning fluid in rectangular ducts, which is encountered in many systems, in particular, in microfluidic and biomedical de…
A numerical framework for linear stability analysis of two-phase stratified pipe flows
Ilya Barmak, Alexander Gelfgat, Neima Brauner
A numerical framework for rigorous linear stability analysis of two-phase stratified flows of two immiscible fluids in horizontal circular pipes is presented. For the first time, t…
Sequence of bifurcations of natural convection of air in a laterally heated cube with perfectly insulated horizontal and spanwise boundaries
Alexander Gelfgat
A sequence of three steady - oscillatory transitions of buoyancy convection of air in a laterally heated cube with perfectly thermally insulated horizontal and spanwise boundaries…
Effect of interface dynamic deformations on instabilities of buoyancy-thermocapillary convection in a two-fluid two-layer system
Alexander Gelfgat
Effect of interfacial disturbances on instabilities of buoyant/thermocapillary convective flows in rectangular cavities is studied in a series of numerical experiments. The computa…
