Effects of Membrane Structure on Oil–Water Separation by Smoothed Particle Hydrodynamics

open access: yesMembranes, 2022
Membrane has been considered an effective tool for oil–water separation. By using the smoothed particle hydrodynamics (SPH) method, the effects of membrane structure on fluid separation were studied thoroughly in this paper. The oil–water two-phase fluid

Theoretical Analysis and Semianalytical Solutions for a Turbulent Buoyant Hydrogen-Air Jet

open access: yesJournal of Applied Mathematics, 2012
Semianalytical solutions are developed for turbulent hydrogen-air plume. We derived analytical expressions for plume centerline variables (radius, velocity, and density deficit) in terms of a single universal function, called plume function. By combining

Effects of Gravity and Inlet Location on a Two-Phase Countercurrent Imbibition in Porous Media

open access: yesInternational Journal of Chemical Engineering, 2012
We introduce a numerical investigation of the effect of gravity on the problem of two-phase countercurrent imbibition in porous media. We consider three cases of inlet location, namely, from, side, top, and bottom.
