In the present study we propose a charge-conservative scheme to solve twophase electrohydrodynamic (EHD) problems using the Volume-of-Fluid (VOF) method. EHD problems are usually simplified by assuming that the fluids involved are purely dielectric (insulators) or purely conducting. Gases can be considered as perfect insulators but pure dielectric liquids do not exist in nature and insulating l...

In Aluminium manufacturing the Soderberg pot is widely used. The study explains about the bubble motion in cryolite liquid in a Soderberg pot anode face using comprehensive VOF multiphase model in FLUENT, under the action of gravitation. The distribution of bubbles introduced under the anodes of an aluminum reduction cell at the initial time has fixed size. 2D simulation results are reported fo...

In order to design packed columns for multiphase operation it is necessary to include reliable data on the flow behavior in the model. Since experiments inside packings are very difficult to perform, CFD simulations are considered to be a sensible approach as numerical experiments. To obtain reliable results validation is inevitable. We present the validation of twoand three-phase film flow und...

Volume of fluid (VOF) methods are extensively used to track interfaces in numerical simulations, and many VOF algorithms require that the interface be reconstructed geometrically. For this purpose, Piecewise Linear Interface Construction (PLIC) technique is most frequently used, which for reasons geometric complexity can slow difficult implement. Here, we propose an alternative neural network b...

In this paper wave transformation in a submerged sloped breakwater and its hydraulic performance was simulated by developing a numerical model in Fortran. The code was established by combining porous flow and a two-phase model using VOF method. Modified Navier-Stokes and k-ε equations implemented to the model to simulate the flow in porous media. Cut cell method was modified to simulate...

gas-lift pumps are devices for lifting liquid phase incorporating the gas phase to be injected in the bottom of liquid column. they are widely used in various industrial applications such as oil extracting in petroleum industries. gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, churn an...
