This paper presents the results of modeling of a microreactor with three inputs geometry (or crow's-feet), in relation to distributions of velocities and concentrations. The objective of this work is the study of this kind of geometry with relation to fluid dynamics behavior, improving the knowledge of microfluidics and microreactors projects. These numerical responses allow conclusions about ...

2-Dimensional Incompressible and Compressible Mantle Convection - new

Changyeol Lee[1]
[1]Faculty of Earth and Environmental Sciences, Chonnam National University, Gwangju, Republic of Korea

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows consideration of mantle compressibility using the CFD Module and I benchmarked COMSOL Multiphysics using ...

The Organizing Committee of the Iberian COMSOL Multiphysics Conference 2014

In the conference we bring together a community that is scientifically diverse in an event about the use of COMSOL Multiphysics. Oral and poster presentations highlight achievements in multiphysics modeling and simulations using COMSOL.

Scraping Non-Newtonian Power-Law Paint

C. R. Meyer [1], J. R. Rice [1],
[1] Harvard University, Cambridge, MA, USA

A similarity solution to Taylor's paint scraper problem for the flow of a non-Newtonian power-law fluid is presented. A shooting method numerical solution agrees with the results found for Newtonian fluids and is able to capture both shear-thinning and shear-thickening fluids. Simulations created in COMSOL Multiphysics® software are also presented to corroborate the shooting method and display ...

Simulating Organogenesis in COMSOL: Towards Efficient 3D Simulations of Organogenesis

D. Barac [1], Z. Karimadini [1], R. Croce [1], D. Iber [1]
[1] Department of Biosystems Science and Engineering (D-BSSE), ETH Zurich, Basel, Switzerland

One of the major challenges in biology concerns the integration of data across length and time scales into a consistent framework: how do macroscopic properties and functionalities arise from the molecular regulatory networks ­ and how do they evolve? A deeper understanding of morphogenesis and organogenesis in particular is required to advance tissue engineering. Recent advancements in 3D ...

Simulation of the Earth's Electromagnetic Clearance System (DEMETER)

J. P. Pothin [1], N. Gosselin [1],
[1] Nexter Systems, France

DEMETER is a magnetic field replicator. This system is designed to deceive anti tank mines. Numerical simulation (using COMSOL Multiphysics® software) allows to indicate DEMETER's performance in various environment and various configurations. The study of the magnetic field provide also an overview of mine-clearing tools disturbances on the field generated by DEMETER.

Studies of Arc Volcanism and Mantle Behavior in Subduction Zones

C. Lee [1]
[1] Department of Earth and Environmental Sciences, Chonnam National University, South Korea

Injection of 3-D hot plume blob develops localized and short-term increases in slab surface temperatures, consistent with the Abukuma adakite, Northeast Japan. 3-D mantle flow develops trough of the lowered slab surface temperatures implying along lowered slab surface temperatures, implying along-arc variations in arc variations in volcanism. COMSOL Multiphysics using the CFD module allows ...

Interpretation of Measurements with Novel Thermal Conductivity Sensors Suitable for Space Applications

[1]Space Research Institute, Austrian Academy of Sciences, Graz, Austria
[2]DLR Institut für Planetenforschung, Berlin, Germany

Thermal conductivity of near surface soil layers is a key parameter for understanding the energy balance of planetary bodies. To measure this property, heated needle sensors are frequently used in field and laboratory applications. To adapt this type of sensors for application on space missions, various modifications have to be implemented. An example for such a modified sensor is the so ...

Numerical Investigation of Electroosmotic Flow in Convergent Divergent Micronozzle
