liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. in this study, a modified hybrid liquid membrane system is introduced. the setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. n-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...

Abstract The instabilities of fluid in the liquid metal battery (LMB) can easily cause a short circuit and lead to safety accidents, which have become bottleneck LMB industrial applications. In this case, structure named grid-structure (GS) based on inner cavity has been used suppress instabilities. Based OpenFOAM-4 x numerical simulation, we analyzed critical electric potential basic structure...

The magnetohydrodynamics (MHD) equations are used to model the flow of electrically conducting fluids in such applications as liquid metals and plasmas. This system of nonself-adjoint, nonlinear PDEs couples the Navier–Stokes equations for fluids and Maxwell’s equations for electromagnetics. There has been recent interest in fully coupled solvers for the MHD system because they allow for fast s...

The "Super-V LCD" (Super View LCD) is a high performance TFT-LCD using high aperture ratio technology "Super-HA(High Aperture)", wide viewing angle technology "Super-VA(Viewing Angle)", interface technology and so on. Super-VA technology has optimized optical parameters and has employed a new technique of alignment control structure of liquid crystal molecules. Super-VA technology obtained wide...

In this study, nanofluid condensation and MHD flow analysis over an inclined and rotating plate are investigated respectively using Least Square Method (LSM) and numerical method. After presenting the governing equations and solving them by LSM, the accuracy of results is examined by the fourth order Runge-Kutta numerical method. For condensation, modeling results show that the condensate f...

In this study, we investigate the steady propagation of a liquid plug in a two-dimensional channel lined by a uniform, thin liquid film. The liquid contains soluble surfactant that can exist both in the bulk fluid and on the air-liquid interface. The Navier-Stokes equations with free-surface boundary conditions and the surfactant transport equations are solved using a finite volume numerical sc...

Because of the most common method of preparing the fuel-air mixture for gasolinefueled engines is port fuel injection (PFI). For reducing the wall-film entering the cylinder in liquid phase, the phenomena of wall-film entering the cylinder in liquid phase should be at minimum lever or be avoided. So the first thing for learning the wall-film is to detect the way of the wallfilm entering the cyl...
