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 ...

This paper is a preliminary design study to develop a hybrid atmospheric icing sensor which have an adequate potential to detect an icing event, icing type and icing rate together with icing load. The physics to detect icing event and icing type have been numerically understood using Debye analytical model. Also the conductivity variations in the Debye model have been understood using modified ...

Air supply hoses are also predominantly used in the medical industry to aid in patient oxygen intake. In many situations, the outside of the hose can be contaminated with chemicals, especially if the hose lies on the ground in an environment where chemicals are easily found. Permeation and transport of chemicals into the walls of air supply hoses is a noteworthy problem in the chemical ...

In recent years, extensive attention has been paid on the application of solar cooling for buildings. Amongst cooling technologies, low-temperature solar-driven adsorption cooling systems are emerging viable alternatives to electricity-driven vapour compression systems. They seem to have a promising market potential. The greatest challenge for their widespread use is the reduced thermal and mass ...

Metal foams are interesting materials with many potential applications. Foamed metals or alloys include gas voids in the material structure and therefore the density is introduced as a new variable, with the real possibility to modify ad hoc their physical properties. In the indirect foaming process carried out in a furnace, simultaneous mass, momentum and energy transfer between three phases, ...

The four foot diameter class A evaporation pan is used by the scientific community as the standard for determining evaporation rates for a number of purposes. The COMSOL Multiphysics® software provides the necessary tools to adequately develop synthetic estimates of evaporation values for input into hydrologic simulation models and other earth science applications. This paper presents ...

A new simple air-cooled inverter design is numerically investigated using COMSOL Multiphysics® software. The thermal-fluid analysis is based on a three-dimensional conjugate heat transfer model in which the flow field is assumed to be laminar. A rigorous mesh convergence was performed to ensure that the overall energy balance error is within engineering accuracy while the computational cost is ...

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 ...

Bread baking is a complex process where various physiochemical and biological transformations take place simultaneously. A two dimensional model was developed for the bread baking process taking into account of volume expansion, heat and mass transfer processes. Phase change and evaporation-condensation mechanism were incorporated by defining thermo-physical properties of bread as a function of ...
