The pore sizes of many membranes being studied for separating the components in gas mixtures are on the scale of nanometers. Depending on the specific gases and pressures being used, this scale will put the flows in the Transition between Slip Flow and Knudsen regime. The differential flow of the gas components gives the relative diffusion of the gases through the membrane. There are a number of ...

UCG is a process which converts coal to syn gas at the underground coal seam itself. UCG can help meeting the rising energy demand by utilizing coal resources that otherwise would be too deep, or of poor quality, or simply not economical to mine. As UCG takes place, a cavity is formed underground in the coal seam which grows three-dimensionally. The objective of this work is to develop a two ...
An Analysis of Heat Conduction with Change of Phase with Application to the Solidification of Copper

The goal of this study was to determine the possibility of using the finite element in COMSOL Multiphysics program to obtain a high accuracy solution to a moving boundary problem, specifically, the solidification of copper. A one-dimensional geometry in Cartesian coordinates was used to investigate the solidification of initially liquid copper from a chilled wall maintained at fixed temperature. ...

Drying is an essential step in many manufacturing processes, for it will have an important impact on the product quality. This is why many numerical models have been realized over decades, in order to predict the hygrothermal behavior of porous media during the drying process. In this paper, we present a model allowing to properly simulate the pressure, heat and mass transfer during the drying ...

Lithium-sulphur (Li-S) batteries have the potential to surpass the energy storage capability of Li-ion batteries due to their high theoretical gravimetric energy density of 2700 Wh/kg. However, the processes which drive the system behaviour are much more complex than those in a Li-ion cell, meaning that controlling them to realise energy densities much above 350 Wh/kg is challenging. In a Li ...
Experimental and Numerical Study of Microbial Improved Oil Recovery in a Pore Scale Model by using COMSOL

A number of visualization experiments are carried out at the laboratory temperature with oil, brine and bacteria suspension for evaluating the performance of MIOR in a glass micromodel. The observations show the effects of bacteria on remaining oil saturation. The interfacial tension reduction, wettability alteration and flow pattern changes are recognized as active mechanisms. COMSOL ...

In this paper we used COMSOL Multiphysics to model basic physico-chemical effects relevant in polymer enhanced oil recovery (EOR) such as non-Newtonian rheology of the displacing phase, permeability reduction, adsorption and salinity effects. COMSOL\'s PDE interface as well as Species Transport in Porous Media interface was used for solving the underlying equations. The validity of the ...

Rechargeable batteries solve electrification and communication problems. As examples, hybrid battery-diesel generator power supplies efficiently power cell towers in remote locations, detached from the power grid. Large battery banks are used to load level user power requirements, reducing stress on power generation infrastructure. Batteries firm the output capacity of intermittent wind ...
