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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

In this paper a pre-study on using COMSOL Multiphysics for rotordynamic analysis is presented. It is concluded that it is possible to use COMSOL Multiphysics to perform rotordynamical analysis. However, there are no standard environment for rotordynamics, hence the user has to extend the ... 詳細を見る

Campi Flegrei caldera is a good example of the most explosive volcanism on the Earth, a potential source of global catastrophes. It has the advantage that the most interesting structural details and main volcanic features appear located at shallower depth, making it a natural candidate ... 詳細を見る

In this context, a one-dimensional acoustic transmission line, exhibiting metamaterial properties, is presented. It is composed of an acoustic waveguide, periodically loaded with membranes having the function of series capacitances, as well as transversally connected open channels ... 詳細を見る
