An Approach to Modeling Vacuum Desorption

C. F. Gomez[1], R. Schunk[1], R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with ... En savoir plus

T. Cavalcanti[1], A. Lima[1], J. Neto[1]
[1]Universidade Federal de Campina Grande, Campina Grande, PB, Brasil

Introdução: A medição adequada de vazão de fluidos é de grande importância nos processos industriais, pois tem implicações diretas na qualidade, produtividade, segurança e eficiência dos processos. Assim, torna-se necessário compreendermos como os fluidos se comportam para baixas ... En savoir plus

Fluid-Structure Interaction of a Double Curvature Arch Dam Under Seismic Loading by the Application of Added Mass Technique and Acoustic Elements

R. Manikandan[1], P. Sultana[1]
[1]National Institute of Technology Silchar, Silchar, Assam, India

Fluid Structure Interaction (FSI) plays an important role in the seismic analysis and the design of Hydraulic structures. In this study, the acoustic finite element model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream ... En savoir plus

Numerical Study of Smoldering Combustion of Activated Carbon in Ⅱ Iodine Absorber

T. Liang[1], M. Liu[1], X. Liu[1], Z. Meng[1]
[1]Safety Engineering, Zheng Zhou University, Zheng Zhou, Henan, China

Iodine absorber is a widely used purification equipment for purifying air in a nuclear power plant. In China, the common type is Ⅱ iodine absorber. Impregnated activated carbon is the main absorber within the iodine absorber. Because of the decays exothermic of radioactive iodine, heat ... En savoir plus

Modeling and Simulation of Membrane Contactor Employed to Strip CO2 from Rich Solvents via COMSOL Multiphysics®

N. Ghasem[1], M. Al-Marzouqi[1], N. A. Rahim[1]
[1]United Arab Emirates University, Al-Ain, United Arab Emirates

A mathematical model is developed for the stripping of CO2 from rich solvent. The rich solvent (aqueous NaOH) is used in CO2 absorption from natural gas through gas-liquid hollow fiber membrane contactor. The polyvinylidene fluoride (PVDF) hollow fiber membrane was fabricated via ... En savoir plus

3D Multiphysics Modeling of Bulk High-Temperature Superconductors for Use as Trapped Field Magnets

M. Ainslie[1], J. Zou[1], D. Hu[1], D. Cardwell[1]
[1]Department of Engineering, University of Cambridge, Cambridge, UK

The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of ... En savoir plus

Evaluation of the Shutdown Time of Subsea Pipeline for Oil Transportation

D. Maciel[1], N. Bouchonneau[1]
[1]Universidade Federal de Pernambuco, Recife, Pernambuco, Brazil

The maintenance plan or rush-to-repair of a subsea pipeline for oil transport may result in the shutdown of the line, in other words, may stop the flow of fluid. During the shutdown, the temperature of the oil tends to decrease continuously, and the heavy molecules tend to crystallize ... En savoir plus

Acoustic-Structure Interaction Simulation of a Differential Phase Sensor

J. H. Lee[1]
[1]Department of Mechanical Engineering, American University of Sharjah, Sharjah, UAE

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... En savoir plus

The report is devoted to implementation, which is a model of an electromagnet. The software tool that is used to model the electromagnet is COMSOL Multiphysics®, a ... En savoir plus

Energy Pile Simulation – an Application of THM-Modeling

E. Holzbecher[1]
[1]Georg-August University, Göttingen, Germany

Energy piles, i.e. heat exchangers located within the foundation piles of buildings, are used for heating of cooling purposes. Although the absolute values of deformations and temperature gradients are low or moderate, the entire setting can be influenced by thermo-hydro-mechanical ... En savoir plus
