Darcian and non-Darcian porous media are characterized by the porosity of medium. To capture miscible viscous fingering in both types of porous media, a new model built with COMSOL® software is presented by coupling of two different physics interfaces (hydrodynamics and transport of solute). For modeling in non-Darcian porous media, Brinkman equation is used. In our simulations, perturbations ...

Reynolds Numbers effect: In the first bend, the higher the Reynolds number, the longer the first pair of vorticities stays attached to the wall. In the second bend, the higher Reynolds Numbers, the secondary flow from the first bend dominates. Curvature Radius effect: The smaller the curvature radius is, the stronger the vorticity magnitude is, and longer it will take for the second pair of ...

In many metallurgical processes metals are (heated and) stirred by an oscillating external magnetic field. The magnetic field induces electric currents in the metal and the currents interact with the magnetic field to create a force, the Lorentz force. For high frequencies induction only takes place in an electromagnetic boundary layer due to the skin effect and the force is confined within this ...

In this paper an axisymmetric model of annular linear electromagnetic induction pumps using numerical methods and four approaches (two transient and two quasi-stationary) with different complexity is studied. Comparison of integral characteristics is performed between numerical approaches and also with analytic estimations. Distributions of physical parameters over length and height of channel ...

The Cutty Sark, built in 1869 in Dumbarton, is the last intact composite tea clipper ship . One of the last tea clippers built she took part in the tea races back from China. These races caught the public imagination of the day and were widely reported in newspapers . They developed from a desire for ‘fresh’ tea and the first ship to return with the new season’s tea could charge a higher ...

Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of associated unknowns. Each formulation has its own benefits and drawbacks; and the optimal may vary depending on the ...

Electric field can bring liquid in motion and thus influence heat transfer. Electro-convection (EC) can be caused by electric forces acting on a liquid, even in absence of space charge. Here, we studied heat transfer in a metal vessel filled by oil, with a submersed high voltage electrode serving as source of heat. Physics involved are Electrostatics and Laminar Flow with Heat Transfer. ...

Aqueous polymers used for enhanced oil recovery (EOR) application is considered a complex fluid. It can exhibit Newtonian and Non-Newtonian behavior depending on the velocity or the stresses that it is submitted during the flooding process. Therefore, the polymer flooding project requires a detailed understanding of chemical and physical process occurred in the porous subsurface reservoir, ...

In this experiment, the performance of a Printed Circuit Heat Exchanger (PCHE) was studied using COMSOL Multiphysics® software. PCHEs are diffusion bonded heat exchangers containing semicircular, chemically etched flow paths. Helium was used as the working fluid on both the hot and cold sides. A simplified model was used in the simulation, and the results were compared to experimental results. ...

The study produced a simulated model of natural convection in an inclined rectangular channel open ended with different locations of radiant barrier (RB) along the channel thickness(S). The upper plate is heated by various uniform constant heat fluxes while the inner surface of the lower plate has a very thin layer with low emissive aluminum foil. This model was used to adjust the location of ...
