The Visualization of Ocean Movement in Southern Ocean

M. M. Saidi [1]
[1] Universiti Teknologi Malaysia, Malaysia

Ocean is the cornerstone in Earth’s system because the surface of the Earth is covered by ocean about 71%. Ocean also holds approximate 97% of the Earth’s water. Ocean is always moving and continuous. This study is focusing on the ocean movement in Southern Ocean which is located in the southernmost of the Earth. It can be called as Antarctica Ocean because it consists of the waters extending ...

An app built with the COMSOL Multiphysics® software allows both expert and beginner users to carry out parametric simulations thanks to flexible and user-friendly customized interfaces. Many people, with or without expertise in numerical analysis, can now access, exploit and share simulation tools, representing a new frontier in virtual prototyping. The investigated topic concerns an industrial ...

Multiphysics Simulation of Space Charge and Electric Field for Liquid Argon Neutrino Detector

S. D. Luise [1], L. M. Bueno [1],
[1] ETH Zurich, Zurich, Switzerland

The DUNE experiment ( is an international collaboration of more than 100 research institutes and universities (among them CERN and Fermilab) which is taking the challenge of building the next-generation experiment for the study of neutrino particles. The detector conceived to detect neutrinos consists of a gigantic cryogenic apparatus able to keep 700,000 tons of ...

Influence of Notches in Corners of Casement Windows on Stress Experienced in the Aluminum Profiles under Thermal Load

J. Arfaoui [1], L. Fromme [1]
[1] University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany

Modern aluminum casement windows consist of an inner and outer profile made of aluminum, which are separated by an insulating bar made of polyamide (see Figure 1). Due to the low heat conductivity of the plastic material the thermal interaction between the living space and the surrounding is reduced significantly, but thermal expansion of the different materials could cause elastic or even ...

Simulation of a Dynamic Scraped Surface Heat Exchanger for Non-Newtonian Fluids

S. Birla [1],
[1] ConAgra Foods, Omaha, NE, USA

Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. One of the factor posing difficulties to heat transfer is viscosity. Highly viscous fluids tend to generate deep laminar flow, a condition with very poor heat transfer rates and high pressure losses involving a ...

Investigation of Performance of SOFC in Hydrocarbon Fuel

S. T. Aruna [1], S. Senthil[1], S. Chauhan [1], B. Shriprakash [1],
[1] CSIR-National Aerospace Laboratories, Bangalore, Karnataka, India.

SOFC is a high temperature electrochemical device known for its fuel flexibility. Apart from using pure hydrogen, it can utilize CO (carbon monoxide), CH4 (methane) or any other higher hydrocarbon. Since methane is highly researched hydrocarbon fuel, it was chosen to start with. The most prominent problem faced while using hydrocarbon fuel in SOFC is the formation and deposition of carbon on the ...

利用高压电容器对单匝线圈放电是产生脉冲强磁场的技术之一,其电路模型简单,可以等效成RLC串联电路,但过程复杂,涉及电磁学、力学、热学、等离子体科学等众多学科。本文分析了其具体过程,并利用 COMSOL Multiphysics® 仿真平台进行了模拟,建立了二维和三维单匝线圈模型,重点研究了线圈的动态特性对磁场分布的影响,并对比了其结果和模型准确性;然后,讨论了线圈的尺寸和所产生磁场的关系;最后通过实验验证了仿真模型的准确性,为今后的相关科学研究奠定了基础。

Microfluidic Separation System for Magnetic Beads

F. Wittbrach, A. Weddemann, A. Auge, and A. Hütten
Department of Physics, Bielefeld University, Germany

It is possible to control the motion of magnetic beads using a combination of hydrodynamic and electromagnetic forces. In this work, we investigate the possibility to manipulate the motion of beads with different magnetic moments in a special microfluidic structure so as to separate them. We also experimentally prove that this structure is a suitable device to separate beads and show that the ...

Shape, Convection and Convergence

R. Pryor
Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

COMSOL Multiphysics software, when properly configured, can readily solve modeling problems in the laminar flow regime using the standard Navier-Stokes equations or in the fully turbulent flow regime using the kappa-epsilon model. Failure to solve a particular model is typically manifested by instability in the calculation and a failure of the model to converge. This paper presents a new ...
