Crust which develops at the surface of meat leads to reactions which affect food color, flavor and safety. Whole pieces of meat are only contaminated by microorganisms at their surface. Thus intense thermal treatment can inactivate pathogenic bacteria; however the associated high temperatures also lead to the formation of carcinogenic compounds. An experimental study of crust development at ...

Silicon carbide (SiC) single crystals are industrially produced by the physical vapor transport technique. Apart from the geometry of the growth setup, there are two main process parameters that can be controlled: temperature and pressure. To support the development of the process, numerical simulation has imposed as the only tool able to describe the process itself, providing a good evaluation ...

Among optical gas sensing methods, photoacoustic (PA) spectroscopy combined with a laser source has proven to be a very robust and sensitive method for trace gas detection. COMSOL Multiphysics® software was used to calculate the frequency response of differential Helmholtz resonator cells in order to optimize the detection limit of PA sensors. Two different kind of simulation were performed: ...

In all implantable medical devices, one main challenge is to assure no water penetrates in the electronic part of the system. To be able to transmit the electronic information from the inside of the device to the lead without any water infiltration, we used a complex part called feed through. This piece is made of four different materials: titanium, alumina, gold and platinum. It is ...

The feasibility of water cooling is investigated for a solid target which is integrated as the inner conductor in a magnetic horn for secondary particle focusing (pi; K) as used in conventional neutrino beam accelerator experiment. A simple axi-symmetric thermal model calculated in COMSOL is used to obtain the temperature distribution inside the target for different values of h; power beam and ...

Electrical Discharge Machining (EDM) is a non-conventional process used for machining electrically conducting materials. In die sink-EDM, sparks are generated between tool and workpiece resulting in heating of both electrode surfaces and creating a melt pool of metal which leads to generation of new surfaces on cooling. Physical processes involved in electric discharge and material removal are ...

Simulation models for steady state thermal hydraulics analyses of ORNL’s HFIR have been developed using COMSOL. A single fuel plate and coolant channel of each type of HFIR fuel element was modeled in three dimensions. The standard k-? turbulence model was used in simulating turbulent flow with conjugate heat transfer. The COMSOL models were developed to be fully parameterized to allow ...

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. Piston rings are often coated to reduce the level of wear on the ring as they will suffer substantial levels of ...

The aim of this work is the numerical study, by finite element analysis using COMSOL Multiphysics®, of the heat transfer and working temperature field of a photovoltaic panel under realistic wind and irradiation conditions. It is well-known that a great portion of the solar radiation absorbed by a photovoltaic module (typically 85% of the incident radiation) is not converted into electrical ...
