A Virtual Laboratory for the 4 Bed Molecular Sieve of the Carbon Dioxide Removal Assembly

R. Coker [1], J. Knox [1], B. O'Connor [1],
[1] Marshall Space Flight Center - NASA, Huntsville, AL, USA

Introduction: Ongoing work to improve water and carbon dioxide separation systems to be used on crewed space vehicles combines sub-scale systems testing and multi-physics simulations. Thus, as part of NASA’s Advanced Exploration Systems (AES) program and the Life Support Systems ... Mehr lesen

Modeling the Acoustic Scattering from Objects Buried in Porous Sediment Using COMSOL Multiphysics® Software

A. Bonomo [1], M. Isakson [1],
[1] Applied Research Laboratories, The University of Texas at Austin, Austin, TX, USA

A frequency-domain finite element (FE) technique for computing the acoustic scattering from axially symmetric fluid-loaded structures subject to a nonsymmetric forcing field based on Ref. 1 is extended to poroelastic media and implemented in COMSOL Multiphysics® software. This method ... Mehr lesen

A COMSOL Multiphysics® Software Analysis of Beam Tube Cooling in the High Flux Isotope Reactor of ORNL

J. D. Freels [1],
[1] Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN, USA

Previous to the present work, a formal calculation was approved [1,2] to support the operation of the High Flux Isotope Reactor (HFIR) Horizontal Beam-Tube 1 of 4 (HB-1). The present calculation [3,4] repeats the previous work using COMSOL Multiphysics® software and extends the analysis ... Mehr lesen

Numerical Modeling of Subsurface CO2-Storage

E. Holzbecher [1],
[1] German University of Technology in Oman (GUtech), Halban, Oman

A model for CO2 storage is presented. It is shown that the system is highly dynamic, i.e. results depend strongly on parameter disturbances and numerical features. However, a series of scenario calculations shows that there are invariants, most important: the duration of the early ... Mehr lesen

Numerical Simulation of Kinetic Interface Sensitive Tracer in Experiment with COMSOL Multiphysics® Software

F. Sun [1], A. Tatomir [1], F. Maier [2], M. Sauter [1]
[1] University of Goettingen, Goettingen, Lower Saxony, Germany
[2] Comsol Multiphysics GmbH, Goettingen, Lower Saxony, Germany

The kinetic interface-sensitive tracers (KIS tracers) are used to give a partial picture of the spreading, mixing and plume migration of supercritical carbon dioxide (scCO2) in the deep saline aquifer by estimating the interfacial areas between scCO2 and brine during the injection of ...

Validation of a CFD Study of Particle Distribution in Nuclear Workplace

P. Geraldini [1],
[1] Sogin S. p. A., Rome, Italy

Understanding the air flow patterns and aerosol trajectories in ventilated rooms can provide key information for determining where to place early warning and monitoring instruments, and how to minimize hazardous materials in the worker’s breathing zone. The dispersion within rooms can be ... Mehr lesen

The Design of a Novel Roof Tile Shape Using CFD Analysis

M. Bottarelli [1], M. Bortoloni [1], G. Dino [1],
[1] University of Ferrara, Ferrara, Italy

In climates with high temperature and solar radiation, reducing the cooling consumption and increasing the standards of indoor comfort are topics of great importance. The roof plays a key role in controlling the indoor thermal comfort. In ventilated roofs, air flow within the ASV (Above ... Mehr lesen

Push or Pull, How Does Silk Flow?

J. Sparkes [1],
[1] University of Sheffield, Sheffield, UK

Silk is one of the longest used and most recognizable textiles that we, as a society, use regularly. We see it as a luxury good, worn as an indicator of success and value. However, despite mankind having domesticated and farmed silkworms for millennia, we still know relatively little ... Mehr lesen

[1] Professorship Micromanufacturing Technology, Technische Universität Chemnitz, Chemnitz, Germany
[2] Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz, Germany
[3] Professorship Micromanufacturing Technology, Technische Universität Chemnitz, Chemnitz, Germany; Fraunhofer Institute for Machine Tools and Forming Technology, Chemnitz, Germany

This study presents investigations on a developed process design for manufacturing internal precision geometries by pulsed electrochemical machining (PECM) with help of multiphysics simulations. Therefore, a 2D axisymmetric transient model was created. The considered physical phenomena ... Mehr lesen

Numerical Study of Thermal Evaporation Unit for Phase Change of Liquid Hydrogen Peroxide to Vapor

[1] Imagine Engineering GmbH, 50126 Bergheim, Germany
[2] Institute of Nano- and Biotechnologies (INB), FH Aachen, Campus Jülich, 52428 Jülich, Germany
[3] Soft Matter and Biophysics, Catholic University Leuven, 3001 Leuven, Belgium

Hydrogen peroxide (H2O2) vapor is a preferred medium of sterilization in different fields of industry. Among the fact that it dissociates to oxygen and water (environmentally-friendly), H2O2 vapor possesses strong mircobicidal and sporicidal characteristics. As such, the use of H2O2 ... Mehr lesen
