Low temperature fuel cells require hydrogen of high purity for electricity production to avoid catalyst poisoning. To purify hydrogenrich flue gases from hydrocarbon steam reforming membrane shift reactors with a metal membranes may be utilized. A model of a tubular membrane shift ... En savoir plus
We have created and optimized a multiphysics model in COMSOL Multiphysics® software that studies sensitivity to ectopeptidase rates in the rat hippocampus. Ectopeptidases are membrane-bound enzymes whose catalytic domains face the extracellular space (ECS) (Figure 1). They have ... En savoir plus
The Huygens Atmospheric Structure Instrument (HASI) was designed to characterize the physical properties of the lower atmosphere and surface of Titan, the planet-size moon of Saturn. The Relaxation Probe (RP) sensor on the Huygens probe, determined the electrical conductivity in the ... En savoir plus
We have developed micro/nano machines such as optically driven micro/nano pumps and spiral-shaped piezoelectric vibration energy harvesters. COMSOL Multiphysics has been used for the design and development of the micro/nano machines. For example, optical force affected to a metallic ... En savoir plus
Nanorobots may be used in the advancement of medical technology, healthcare, and environment monitoring by swimming in biological fluids flowing in narrow channels of a few hundred nanometers in the area of bio-medical engineering. The pronounced effects in nanometer scale such as ... En savoir plus
Excessive air damping can be detrimental to the performance of oscillating MEMS components. Complex systems, such as structures in pre-etched cavities or angular comb-drive scanning mirrors, typically require simulations to reliably evaluate the air damping. The simulated and ... En savoir plus
The computational ability to accurately predict the dynamic behavior of a nuclear reactor core in response to reactivity-induced perturbations is an important subject in reactor physics. Space-time and point kinetics methodologies were developed for the purpose of studying the transient ... En savoir plus
Offshore wind and wave energy industries have developed considerably in the last two decades. Most offshore energy structures used in the existing projects are mono-piles in shallow water due to simplicity of installations, design and control. Numerous research for the design and ... En savoir plus
Mathematical description of microwave drying requires the solution of two different physics: electromagnetics in the microwave oven cavity and food material and, transport process (mass, momentum and heat transport) in the food material. Maxwell’s equations for electromagnetics were ... En savoir plus
CFD simulations were carried out to predict the convective heat and mass transfer coefficients in the rice bed, and correlations were developed for the convective heat and mass transfer coefficients as a function of drying air flow rate. The developed correlations were used to extend the ... En savoir plus
