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 ...

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 ...

Within projects of geothermal energy, we need hydrodynamic and thermal modeling to forecast the impacts of geothermal deep wells on existing wells. In case of pumping and reinjection of the geothermal fluid in a deep groundwater reservoir, located in a sedimentary basin with lateral and vertical lithology variations and major faults, it is fundamental to understand the behaviour of the ...

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, ...

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 ...

Our safety analysis group in the Research Reactors Division of Oak Ridge National Laboratory supports a project to investigate the production of Pu-238 isotope for missions of deep space travel in the High Flux Research Reactor. COMSOL Multiphysics® has been used to support this activity in the past, and we have successfully installed and irradiated three different target designs. The gas-gap ...

Metal foams are interesting materials with many potential applications in engineering. Foamed metals or alloys include gas voids in the material structure with the real possibility to modify ad hoc their physical properties. Following our previous efforts aimed to simulate and study the foaming process of a metal, we propose in this work a model which considers heat and mass transfer ...

Fluid injection in deep wells is a basic procedure in geothermal permeability enhancement. The retrieved changes of Pressure and Temperature are subsequently considered as sources of incremental stress and strain changes, using the elastic model from COMSOL Multiphysics®, which are then converted to Coulomb stress changes on favoured faults, taking into account also the background regional ...

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 ...

COMSOL Multiphysics® software is used to model the field joint application process on carbon steel pipelines for deep sea crude oil transportation, taking into account not only heat transfer, cure kinetics, and crystallization, but also thermal, cure and crystallization shrinkage and the resulting interfacial thermal stresses. Experimental data from the raw materials are implemented in the model ...
