Steam methane reforming is a widely studied process because of its importance for hydrogen production. A two-dimensional membrane-reactor model was developed to investigate the steam-methane reforming reactions. The use of membrane as membrane-reactor separator offer us few advantages because it help in continuously removing the hydrogen from the reaction zone, shifting the chemical equilibrium ...

Use of COMSOL Multiphysics: In operation, the piston ring is surrounded by gas acting on it, using effect of chamfer design has been considered using Love’s equation in conjunction with Stone’s equation for force ad Miler’s equation for gas pressure modelling. The chamfer geometry was controlled through variable inputs such as coating thickness, ring thickness, distance from the ring angle ...

This paper addresses the study of thermal behavior of thermoset polymer matrix filled with microparticles. A numerical model was developed with COMSOL Multiphysics to get a random spatial distribution of fillers in a representative volume element (RVE). This model was then compared to an analytical reference model (Hamilton model) and experimental results. This comparison highlights a good ...

The dynamic behavior of cable supported bridges subjected to moving loads and affected by corrosion and accidental failure mechanism in the cable suspension system is investigated. The different types of cable supported bridges are distinctively characterized by the configuration of the cable system . The suspension system comprises a parabolic main cable and vertical hanger cables connecting ...

Nanoscale zerovalent iron is a promising reagent for the remediation of contaminated groundwater. The aim of the study is to simulate the transport of iron nanoparticles and their interaction with the porous media, their attachment and deposition on the soil grains. The particles trajectories is determined by several forces, some of them are significance only close to grains surfaces where, ...

Ammonia separation from water by membrane contactor was simulated on transient state and compared with experimental data. Aqueous low concentrated solution of ammonium with high pH has been pumped inside the hydrophobic hollow fibers, acid solution in the outside part. The system is in closed loop configuration. In order to simulate the separation process, equations were developed considering ...

Modular orthopaedic devices are a feature of total joint replacements today. These modular orthopaedic devices allowing surgeons to choose from a variety of available implant sizes, designs & material options for the procedure required and the patient specific requirements. However, even though this allows for greater scope of implant construction, if the various components of the modular design ...

The contrast between hydro-mechanical behavior of the rock matrix and fracture network systems results in flow partitioning between fracture and matrix systems which is affected by the In-situ stress regime. Fracture flow, Darcy law and free and porous media flow physics interfaces of COMSOL were used in simulating a fractured core flooding test to achieve a better understanding of flow ...

A field of connected boreholes can be used both for cooling, heating and storage purposes. The boreholes transfer heat to or from the ground, which over time changes the temperature in the ground. It is important that the borehole field is properly sized and evaluated before the construction. This study presents results from borehole field evaluations of inclined boreholes used for cooling ...

In this work we solve a model to simulate the drying of potatoes slices. The model considers both the transport of free and vapor water by applying a mechanistic approach. The critical moisture point (CMP) was considered, since it is a transition zone and it represents the point where water saturation is near from cero and hygroscopic domain begins. The CMP divides the hygroscopic and ...
