The transition to sustainable production includes the reduction of fossil material usage. Vegetable oil can be used as a reagent to form polyurethane by epoxidation through three major reaction steps, epoxidation, carbonation, and aminolysis. Many attempts have been made to model these ... En savoir plus
ABSTRACT: Over the years, the most common method of preventing scale formation and blockage of formation pores in oil and gas systems is by squeezing of chemicals into the formation. Different experimental and simulation studies have been carried out to understand the interaction of the ... En savoir plus
Study of interaction of drops and bubbles with electric field is important for understanding the physics involved in various physical phenomenas and industrial processes. Important applications arise in colloidal systems (Miller and Scriven, 1970), meteorology and cloud physics (Sartor, ... En savoir plus
Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosified water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three ... En savoir plus
Mutually soluble-solvents can improve the ultimate recovery in conventional reservoirs. Initially, the solvent moves with the imbibing aqueous phase into the reservoir. However, upon contact with oil, diffusion occurs and the solvent is transported in the oleic phase. Through the ... En savoir plus
Sedimentation is a challenging two-phase problem to model and simulate. Many applications in the industry use sedimentation for separation. For example treatment of wastewater often carried out in settling basins. Different types of the sedimentation process include independent and zone ... En savoir plus
Markus Zahn received all his education at MIT, was a professor in the Department of Electrical Engineering at the University of Florida, Gainesville from 1970-1980, and then joined the MIT Department of Electrical Engineering and Computer Science faculty in 1980. He works in the ... En savoir plus
This work presents a small swimmer model in a low Reynolds number ($Re$) environment governed by the equation of motion for Stokes flow in COMSOL Multiphysics®. The entity, a few centimetres helical robot, is located inside of a pipe full of silicone oil, where the forces caused by the ... En savoir plus
Food pastes generally consist of a viscous liquid phase in which a high concentration of solid fillers is embedded and their production often includes a dosing step that involves high speed extrusion. Due to the high volume fraction of solid fillers, this extrusion is not only subject to ... En savoir plus
OCAS is a joint venture between ArcelorMittal and the Flemish Region. She uses COMSOL Multiphysics for the following: Enamel solidification Magnetic Pulse Forming Electromagnetic modelling of electric machines Vortex Induced Vibrations Model Identification for Orthotropic Materials and ...
