Helmholzt-Zentrum Geesthacht
Geesthacht, Germany

In proper designs of hydrogen storage systems based on metal hydrides three processes are modelled and simulated: hydrogen flow (through the metal hydride bed), solid-state chemical transformation, and heat transfer (due to the highly exothermic chemical transformation). In this work, ... Read More

Modeling Revitalization of Atmospheric Water

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

Developments intended to improve system efficiency and reliability for water and carbon dioxide separation systems to be used on crewed vehicles combine sub-scale systems testing and multiphysics simulations. This paper describes the development of COMSOL Multiphysics® simulations in ... Read More

Fully Coupled FEM Modeling of the Swelling Behavior of Human Intervertebral Disc in Response to a Change in Chemical Environment

G. K. Mistri[1], K. J. Suthar[2]
[1]Department of Mechanical and Industrial Engineering, University of Illinois at Chicago, Chicago, IL, USA
[2]Advanced Photon Source, Argonne National Laboratory, Argonne, IL, USA

The swelling behavior of human intervertebral disc is strongly influenced by chemical changes in the surrounding environment. Swelling of IVD is governed by various physical phenomena, including chemical and electric potential based transport, electrical charge balance, and swelling due ... Read More

Linear Convection and Conduction in Cylinders of Water Exposed to Periodic Thermal Stimuli

R.E. Tosh[1], and H.H. Chen-Mayer[1]
[1]National Institute of Standards and Technology, Gaithersburg, Maryland, USA

Primary reference standards for determining absorbed dose to water in radiotherapy beams used at cancer clinics and hospitals ultimately must make reference to the temperature change in water produced by ionizing radiation. The most direct experimental technique for this purpose is water ... Read More

Modeling of Atmosphere Revitalization

R. Coker[1], J. Knox[1], K. Kittredge[1]
[1]NASA - Marshall Space Flight Center, Huntsville, AL, USA

All spacecraft systems must be minimized with respect to mass, power, and volume. Here, we focus on current efforts to improve system efficiency and reliability for water separation systems to be used on crewed vehicles. These development efforts combine sub-scale systems testing and ... Read More

Blistering of Industrial Floor on Concrete Substrate: the Role of the Air Overpressure

S.V. Aher[2], P. Devillers[1], G. Fau[3], B. Tranain[3], and C. Buisson[1]
[1]Centre des Matériaux de Grande Diffusion, Ecole des Mines d’Alès, Alès cedex, France
[2]Indian Institute of Technology Kanpur, Kalyanpur, Kanpur, Uttar Pradesh, India
[3]Centre Scientifique et Technique du Bâtiment, France

Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of ... Read More

The Simulation of Flow and Reduction of NO in a Heterogeneous Reactor.

O. Śliczniuk [1], B. Olejnik [1],
[1] Wrocław University of Technology, Faculty of Chemistry, Department of Chemical Engineering, Wrocław, Poland

Nitrogen oxides are one of the more dangerous ingredients contaminating the atmosphere. They are considered to be almost ten times more harmful than carbon monoxide, and sulfur dioxide several times. A whole range of photochemical reactions involving nitrogen oxides are responsible for ... Read More

Study of Particle Collection Using Magnets

M. D. Cheng [1],
[1] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Airborne particles or aerosols are an unstable system with distributed properties among its individual particulate members. Its fundamental property such as particle size, composition, electrical conductivity, magnetic susceptibility, and morphology could change in response to ... Read More
