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 is generated in the adsorption process. Carbon is a combustible material. Moreover, air is always supplied in ...

A computer simulation model was developed using finite element-based commercial software, COMSOL Multiphysics®, to simulate temperature distributions in wheat samples packed in a rectangular plastic container and treated in a 6 kW, 27.12 MHz RF system with and without mixing conditions. The developed model was then experimentally validated by temperature distributions of three layers without ...

REBCO tapes belong to a class of high-temperature superconductors (HTS) that can be superconducting at liquid nitrogen temperatures (77K) as opposed to typical superconductors such as Nb3Sn which need to operate at liquid helium temperatures (4K). One important aspect of designing a super conducting coil is the ability to predict the critical current above which the conductor becomes ...

As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a photocatalytic oxidation or PCO reactor into continuous flow. PCO technology is very cost-effective, efficient ...

Parametric finite element simulations were performed to study the effect of film thickness, and electrode size on the different impedance parameters for insulating thin films deposited on a conductive substrate. COMSOL Multiphysics® was used to solve the quasi-static form of Maxwell’s electromagnetic equations in time harmonic mode. Several types of 2D models (linear and axisymmetric) ...

A scientific hypothesis states that cryogenic trapped water is just under the surface of lunar soil at the poles in permanently shadowed craters. Microwave energy can be used to efficiently extract this water from permafrost. COMSOL permits calculation of the heating of simulated lunar soil using measured temperature dependent dielectric properties. Calculations at different microwave ...

Accurate bipolar-plate and flow-field layout is one crucial task for optimizing fuel cells. These cell components perform several functions, including charge transport or gas and water transport throughout the cell just to name a few. Overall, the design depends on the fuel cell application or the geometrical size of the assembly. The requirements for a flow-field used in a high temperature ...

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the electromagnetics, the electronics (including the control of the process), the mechanics and the fluidics with respect to ...
