The understanding of the tracer migration in two-phase porous media systems and its reaction over the fluid-fluid interfaces is a challenging task important for a number of engineering applications, e.g. oil recovery, carbon capture and storage in geological reservoirs, remediation groundwater contaminations, etc. The goal of this work is to implement in COMSOL Multiphysics® an immiscible two ...

Flexography is a roll-based mass printing process used in manufacture of printed products such as sensors, self-cleaning surfaces, and flexible electronics. Flexography involves inking of a stamp wrapped around a roller, and the transfer of ink on the stamp surface to a printing substrate as the roller rotates against it. Ink transfer ratio from the stamp surface to the printing substrate is ...

COMSOL Multiphysics® is used in this study to simulate the flow around a square cylinder and focus on reducing the forces on the cylinder by passive control methods. Numerical simulations are made to find optimum cases of control methods that guarantee maximum reduction for Reynolds number 160 based on the width of the square cylinder (W) and the inlet flow velocity (U_in). The selection of the ...

Macroscale ultrasonic separation is a new filtration technology, with various applications such as cell clarification, cell therapy, blood-lipid separation, oil-water separation etc. These systems use piezoelectric transducers to create standing waves in fluid-particle mixture. Suspended particles get clustered by action of acoustic radiation forces and are separated out by enhanced gravity ...

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 ...

Stockton University has one of the largest closed loop geothermal system in North America. It provides heating and cooling for the university academic facilities. The well field comprises of a grid of four hundred wells bored to a depth of 130m. The ground is composed of three aquifers of saturated sand sandwiched between confining beds and transition layers of sand and clay. The purpose of this ...

Adiabatic compression of gases can work as an ignition source and is still one of the main causes of accidents in chemical plants processing tetrafluoroethylene (Reza and Christiansen, 2007). The ignition of tetrafluoroethylene induced by adiabatic compression has been studied experimentally with a setup which allowed for the rapid opening of a high speed valve connecting two portions of a ...

The high flow rate within the HFIR cooling water flow channel causes the fuel plates to deflect which in turn, changes the coolant flow characteristics. This nonlinear feedback loop between the coolant and the fuel plate is the focus of the present simulation of the fluid-solid interaction between the coolant flow and the fuel plates to accurately predict the plate’s deflection using the Fluid ...

This paper explores the complexities of a dragonfly's flapping wing motion. It includes the literature as well as analytical results using simulations done in COMSOL Multiphysics® software. The study depicts the Fluid-Structure Interaction of the 2D wing (airfoil) with air, governed by Naiver-Stokes equations. The wing follows mathematical functions and is given motion similar to dragonfly's ...

One of the most critical aspects on water electrolysis is gas-liquid separation, especially in systems with forced convection. The main problem of this kind of circulation is that a gas fraction could return to the electrolysis circuit. A suitable design of separator devices could be a solution in order to avoid a gas return to the electrolysis circuit. In this sense, the use of deflectors might ...
