Small nuclear ribonucleoprotein particles (snRNPs) are essential supramolecular complexes involved in pre-mRNA splicing, the process of post-transcriptional RNA modifications. The particles undergo complex assembly steps inside the cell nucleus in a highly dynamic compartment called the ... Read More

A Numerical Investigation on Active Chilled Beams for Indoor Air Conditioning

G. Cammarata, and G. Petrone
Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy

In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational ... Read More

Numerical Study of Microfluidic Fuel Cell Performance

A. E. Khabbazi[1], A.J. Richards[1], and M. Hoorfar[1]
[1]School of Engineering, UBC Okanagan, Kelowna, BC Canada, Canada

Using COMSOL Multiphysics 3.5, a numerical model has been developed to determine the effect of the channel geometry and electrode configuration on cell performance based on polarization curves. The Butler-Volmer equation was implemented to determine the reaction rates at the electrodes. ... Read More

Simulation of DC Current Sensor

K. Suresh, B.V.M.P.S. Kumar, U.V. Kumar, M. Umapathy, and G. Uma
National Institute of Technology Tiruchirapalli, Tamil Nadu, India

A proximity DC current sensor using of a piezo sensed and actuated cantilever beam with a permanent magnet mounted at its free end is designed and simulated in COMSOL Multiphysics. The change in resonant frequency of cantilever is a measure of the current through the wire. The sensor is ... Read More

COMSOL Modeling of Groundwater Flow and Pollutant Transport in a Two-Dimensional Geometry with Heterogeneities

University of Maryland Baltimore County
Baltimore, MD

The Delmarva Peninsula is located on the East Coast of the United States, between the Chesapeake Bay and Atlantic Ocean. Industrial farming in the Delmarva Peninsula leads to levels of nutrients nitrogen, which grossly exceed natural levels and greatly impair the health of the bay. The ... Read More

University of Pannonia
Department of Process Engineering
Veszprém, Hungary

With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research ... Read More

Heat and Mass Transfer in a Gypsum Board Subjected to Fire

B. Weber
Swiss Federal Laboratories for Materials Science and Technology
Duebendorf, Switzerland

Heat and mass transfer through a gypsum board exposed to fire is simulated and compared to experimental data. The gypsum board is modeled as a porous medium with moist air in the pores. A dehydration front develops at the fire side and travels through the board, consuming energy and ... Read More
