Using COMSOL® 3.5a, models were created to simulate the heat transfer between the working fluid and the selective coating as well as the natural convection of the working fluid itself. In these models, a constant heat input on half of the selective coating facing the sun was considered as energy input from the sun, and the open end of the tube, where the working fluid can flow in and out of the ...

The mass and recoverability of oil and gas in unconventional reservoirs strongly depend on the understanding the petrophysical properties of the rocks at a large range of scales. Three-dimensional imaging is capable of unveiling the detailed microstructures within the rocks down to the nanometer scale. Using a multiscale imaging protocol, a Devonian shale rock sample with heterogeneities is ...
Multiphase Transport with Large Deformations Undergoing Rubbery-Glassy Phase Transition: Applications to Drying

Drying of biomaterials such as foodstuffs involves mass, momentum and energy transport along with large shrinkage of the porous material, which have significant effects on their final quality. Foodstuffs exhibit non-linearity when undergoing large deformations that affect the transport process in a critical way. Thus, it becomes important to perform a two-way coupling of the multiphase transport ...

Electromagnetic waves in the terahertz (THz) region may be useful for non-destructive imaging and biosensing technology. This presentation shows the example of our research aimed at the development of application in the THz region. The result of comparing the FDTD method and COMSOL Multiphysics is demonstrated in the investigation of metamaterial and the photoconductive antenna.
Analysis of Temperature Distribution in a Magnetite Catalyst Bed under Microwave Irradiation using COMSOL Multiphysics®

Dehydrogenation of ethylbenzene with a magnetite catalyst has been performed with a fixed bed flow type reactor under microwave irradiation. Microwave heating showed a temperature gradient in the catalyst bed. We analyzed an electromagnetic field and heat transfer in the microwave cavity using COMSOL Multiphysics to visualize the temperature distribution in the catalyst bed.

Introduction Electromagnetic stimulation is a common therapy to support bone healing in cases of avascular necrosis or pseudarthrosis. An electrostimulative screw implant (Asnis III s-series screw in Figure 1) is used to stimulate bone regeneration in the treatment of femoral head avascular necrosis. To enable positive outcome of the treatment, optimal positioning of the electric implant is ...

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows consideration of mantle compressibility using the CFD Module and I benchmarked COMSOL Multiphysics using ...

Ion implantation in insulating materials leads to local variations in mechanical and optical properties that can be exploited for the fabrication of micro-structures. In particular, ion irradiation of diamond causes the formation of buried amorphised layers, with correspondent mass density and refractive index variations that depend on the level of “damage” of the crystal structure. ...
