A 3D finite element analysis is carried out, using COMSOL® software, to reproduce the thermal profile obtained with Rosenthal’s equation. The implemented heat transfer equation has been modified as a means to approximate Rosenthal’s solution. An analysis of the differences between the simulation and Rosenthal’s solution, when the geometry of the domain and the source are changed, has been ...

The dynamic behavior of droplet impingement on a solid surface is important to many engineering applications. This paper studied the dynamic behavior of a droplet impinging onto solid dry surfaces with different surface wettability using the COMSOL Multiphysics® software. The simulation results were validated against experimental results. It was found that the Level Set method can predict the ...

A comprehensive mathematical model that includes mass and heat transfer was developed for the transport of gas mixture of carbon dioxide and methane through hollow fiber membrane (HFM) contactor. COMSOL Multiphysics® was used in solving the set of partial, ordinary and algebraic equations. The model was based on "non-wetted mode" in which the gas mixture filled the membrane pores for ...

THM (Thermo-Hydro-Mechanical) behavior of the reservoir during SAGD (Steam-Assistant-Gravity-Drainage) was studied through a proper constitutive modeling of the porous media. Specifically, a generalized density-stress-fabric dependent elasto-plastic model with stress-dilatancy and plastic damage as main ingredients was implemented into COMSOL Multiphysics®, to model geomechanical behavior during ...

The major steps in the beer making process are simple and with some skill, rather good brew can be produced using a common picnic cooler. First, grain (usually barley) is wetted and allowed to partially germinate before dried in a kiln (malting) Next, during mashing in a mash tun reactyor the malted grains are soaked in hot water in to extract the fermentable sugars and then rinsed slowly to ...

Introduction: Development of next-generation chemical processes that have zero emissions is a key environmental objective for sustainable development. The manufacture of H2SO4 by the air oxidation of SO2 to SO3 is an important technology where an opportunity exists for new catalyst development and process innovation by reducing emissions of unconverted SO2 in process reactor tail gases owing to ...

Recent studies have been devoted to develop mathematical models to simulate the food processing using the porous media approach. The aim of this study is to simulate the microwave drying of osmodehydrated food by means of modeling the mass, energy and momentum transfer using the porous media approach. Microwave drying involves complex physical mechanisms which should be taken into account in the ...

During the hydraulic fracturing process, there can be possible re-activation of closed/sealed faults and natural fractures in the formation, which may lead to changes in the boundary conditions of the reservoir. While study models of shale gas formations have utilized the concept of a closed reservoir in order to optimize the production of gas in the well-bore, this assumption cannot be adopted ...

We present simulations of drops spreading on heterogeneous surfaces. The droplet height is the solution of a time-dependent non-linear fourth order partial differential equation, which is solved using COMSOL Multiphysics. In the fully wetting case, we compare our results with experimental data and with previous results reported in the literature. The simulation results reveal how ...
