The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics computer simulations for evaluation and optimization of subsystem approaches. In particular, this paper describes ...

In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational conditions, are principally produced as temperature and velocity distributions. Special attention is paid to the ...

This study aims to numerically investigate on a passive solar system for indoor heating called as \"Trombe wall\". The transient buoyancy driven flow characterizing that system and the thermal distribution are solved by numerically integrating the governing equations in COMSOL Multiphysics environment. Simulations are carried-out for a time range corresponding to 12 days. The results are ...

Our Institute at the West Hungarian University is dealing with modelling of heat physical treatments in agricultural (biological) materials. The essential key in order to gain accurate results is to know the driving forces during heat and mass transfers. In case of mass transfer processes the application of moisture gradient as driving force gives false results. Therefore, we use water ...

Photothermal therapy through Gold Nanorods (GNRs) is a new approach for the minimally invasive treatment of cancerous tissue. In order to design the proper settings, it is important to study the thermal effect that are induced close to the nanoparticle (nanoscale model), in the close vicinity and in the cancerous tissue (microscale model). A temperature dependent 2D-model of this particular ...

Divertor is act as an exhaust for the nuclear fusion reactor. Main function of a divertor is to remove the heat flux from the plasma. Plasma facing components of the divertor are made up of Carbon (Graphite/CFC) and tungsten like materials. Hence these materials are exposed to the transient heat loads up to 10MW/m^2. Thermo mechanical behavior of Graphite test mock-up under the transient heat ...

Usually, in integrated circuits, the chip is brazed on leadframe and then, a polymer resin is molded around to create the packaging. On the first hand, the molding process at high temperatures will induce thermomechanical stress on the chip. As the leadframe, the chip and the braze have all different thermoelastic properties, these stress can be critical for the chip connections. To ...

The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by-product of olive oil production. The modelling includes the PEF effects on the WOP which is flowing through a ...

A solidification process of casting explosives in shell is studied in this paper. An enthalpy method approach is used to model the solidification process. Both the thermal and mechanical effects are taken into account. An ALE (Arbitrary Lagrangian-Eulerian) method is used to represent the physical deformation due to solidification. Results from the model are verified against experimental ...

Hunting Lodge St. Hubertus is one of the most prominent Dutch buildings from the early twentieth century. An extensive study of wind and wind-driven rain (WDR) was conducted to provide insight into the moisture load of the building facade, using measurements and CFD simulations. COMSOL Multiphysics was also used for modeling the moisture transport through the walls of the tower. The model ...
