COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ...

One way of storing thermal energy is through the use of latent heat energy storage systems. One such system, composed of a cylindrical container filled with paraffin wax, through which a copper pipe carrying hot water is inserted, is presented in this paper. It is shown that the physical ... Per saperne di più
A 1D phase change problem, known as Stefan’s problem, for which analytical solutions are available, is solved as a 2D problem using COMSOL Multiphysics. The PCM medium is semi-infinite, initially solid at its melting temperature Tm, and at t = 0, the wall temperature is raised to Tw > ... Per saperne di più
This paper presents some results of numerical simulations carried out to investigate the basic hydrodynamic interactions between the laminar flow in the water column above triangular bedforms and the Darcian flow in the underlying permeable sediments. The flow was described by the Navier ... Per saperne di più
The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... Per saperne di più
Simulations of streamer discharge was performed by utilizing a space adaptive numerical scheme based on logarithmic representation of mass conservation equations, which governs the transport of charge carriers. Implementation of a model, which describes the propagation of a streamer in ... Per saperne di più
Stress and failure in the earth have long been observed to couple to hydrogeology. Poroelastic models, introduced by soil scientists, can account for strong two-way coupling between porous crustal rock formations and their pore fluids. Current efforts to provide new energy resources ... Per saperne di più
Non-Newtonian laminar flows in curved circular tubes with inserts are investigated by computer simulations. 0.65% solution of NaCMC is considered. Three-dimensional incompressible Navier-Stokes equations are solved using COMSOL Multiphysics. Placements of inserts inside the curved tubes ... Per saperne di più
The method to derive upscaled expressions for the dispersion coefficients for reactive flow in a porous medium uses a periodic unit cell (PUC), which consists for instance of a spherical grain in a cube, but nothing prohibits defining more complex PUC's. Homogenization leads to a coupled ... Per saperne di più
Pore-scale modeling of multiphase flow through porous media is addressed most frequently to improve our understanding of flow and transport phenomena in such settings. It can be used to obtain macro-scale constitutive equations, to assign multiphase flow properties in large scale models, ... Per saperne di più
