Effects of Forced Airflow Cooling on Laser Beam Heating of Volume Bragg Gratings
Forced airflow cooling of a Volume Bragg Grating heated by a laser beam was investigated by means of simulation with COMSOL Multiphysics®. In addition to air cooling of unrestricted airflow, a case of airflow directed by limiting glass plates was investigated. A number of temperature ... En savoir plus
Optical and Electrical Modeling of Three Dimensional Dye Sensitized Solar Cells
Dye sensitized solar cells (DSSCs) have received tremendous attention as alternative photon harvesting devices. While the sintered TiO2 nanoparticle network attached with dye molecules achieves efficient photon absorption, the electrons have to diffuse through the long TiO2 network to ... En savoir plus
Numerical Investigation for the Effect of Guide Panel on Heat Transfer from Steel Containment
In a nuclear reactor, the containment is the last barrier for the release of radioactivity during severe accident conditions. Containment material can be concrete or steel or steel-lined concrete. Steel containments have a high load bearing capacity and a high degree of leak tightness at ... En savoir plus

Comparison Between Flow Simulations and Foam Experiments in Porous Media
Recovery of oil by gas injection is usually inefficient due to the low viscosity of the gas, which results in bypassing of the oil. By adding surfactant solutions it is possible to get in-situ foam formation. Foam has a much higher “viscosity” and hence does not bypass the oil, leading ... En savoir plus
