In this study, COMSOL Multiphysics is applied in order to simulate reacting flows for duct burner systems arranged in the post-firing section of a Heat Recovery Steam Generator of a combined cycle power plant. Two- and three-dimensional simulations are carried out in order to investigate on operative conditions mainly responsible of duct burners overheating. The results are obtained for several ...

Heap leaching in the mining industry had become a sophisticated practice at least 500 years ago. It is a mineral processing technology whereby piles of crushed Run-of–Mine rock are leached with chemical solutions to extract minerals. The goal of this work is to contribute to the understanding of the behavior of a heap leach pad by using coupled Hydro-Mechanical-Chemical simulations. COMSOL ...

Gaseous exhaust of different industries contains dust particles of different chemical precipitates that are harmful for the environment. Electrostatic Precipitators are very often used in industries like power plant to filter their gaseous exhaust and to prevent the atmosphere to being polluted. Electrostatic Precipitators are very efficient in dust particle collection from the flue gas. ...

There is a great need for an effective drug treatment of the posterior eye, as the major reason for visual disability in industrial countries is Age-related Macular Degeneration (AMD). In USA alone, there are almost 2 million people affected by AMD . A virtual pharmacokinetic 3D model of the human eye is built to address this problem, using COMSOL Multiphysics® software, based on the Finite ...

In this paper describes an original method for indirect measurement of the vapor pressure and temperature in the keyhole in electron beam welding. This method is based on the determination of the concentration of chemical elements in the vapor above the welding zone. Taking into account these data model is built 2D diffusion processes with heat and mass transfer elements in the melt, which ...

Steam Reforming of Ethanol using a Catalytic Wall Reactor (CWR) was successfully studied using COMSOL Multiphysics. A mathematical model was used to describe the reactor performance in terms of the main variables and dimensionless groups. Simulations showed that at specified conditions CWR maintains a thermal performance adequate for evaluating catalysts under a uniform temperature profile. CWR ...

Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of storage is based on a clay formation with low permeability, homogeneity and continuity (i.e Callovo-Oxfordian ...

The water storage reservoir at the WTP Noardburgum is used to even out demand and supply and ensure a stable drinking water production capacity. At the moment the rectangular reservoir has a single pipeline which serves as an inlet during the fill cycle and as an outlet during the draw cycle. This study aims to examine the current mixing characteristics of the reservoir and to investigate ...
