An analysis to quantify the flow inside the narrow channels of an ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) adsorbent bed is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Heaters and associated fins inside the adsorbent beds form many small parallel channels which are rectangular in cross section. The channels are ...
A COMSOL Multiphysics® Software Interface with GEMS3K for Modeling Reactive Transport (Geo)Chemical Processes
O. B. Isgor , V. J. Azad ,
 Oregon State University, Corvallis, OR, USA
This paper presents a generic interface for reactive transport process modeling that was developed between the COMSOL Multiphysics® software Java API (transport model) and GEMS3K (reaction model). While the transport of different species, kinetics of dissolution/precipitation, system potentials, fluid and gas flow, etc. can be modeled in a complex chemical system with COMSOL® software, the ...

Spray drying is a common drying technique in food industries to convert liquid to powder form. A good understanding on the dynamic behavior of the process is important to ensure proper control. The aim of this study is to develop empirical models for spray drying of whole milk powder and orange juice powder. A preliminary study on the effect of several inputs such as inlet air temperature, feed ...

Temperature and residual moisture content of a stationary Textile in a home tumble dryer are simulated in a 2D model with COMSOL Multiphysics. Moisture migration to the textile surface is modeled in the form of capillary flow and vapor diffusion along with heat transfer in the form of conduction and energy lost due to phase change (evaporation). The drying air energy, mass and momentum transport ...

High-power couplers working at 350 MHz for particle accelerator cavities are presently under development in the LEHIPA project at BARC. It is important to analyze RF losses on conducting surfaces and resulting thermal profiles. COMSOL Multiphysics® is used to study these coupled RF-thermal effects and estimate cooling requirements for these couplers. The RF loss on the copper conductors and ...

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding with analytes in patient samples in order to generate a visual signal if disease-specific antigen is ...

With the extensive application of ground freezing method in coastal areas, the groundwater environment during ground freezing has been changed. Especially in seawater intrusion areas, groundwater salinity is high (even salinity equivalent to sea water (ca. 35g/L)). Engineering experience shows that the presence of saline groundwater will affect the formation of freezing wall. High groundwater ...
Using COMSOL Multiphysics to Model Crust Development at the Surface of Whole Beef Meat Subjected to Hot Air Jet

Crust which develops at the surface of meat leads to reactions which affect food color, flavor and safety. Whole pieces of meat are only contaminated by microorganisms at their surface. Thus intense thermal treatment can inactivate pathogenic bacteria; however the associated high temperatures also lead to the formation of carcinogenic compounds. An experimental study of crust development at ...
