Use of COMSOL Multiphysics® Software for Physics Laboratory Exercises

H. van Halewijn [1],
[1] Fontys Hogeschool, Applied Physics, Eindhoven, Netherlands

COMSOL Multiphysics® is used to simulate thermal flow experiments at out University for Applied Physics. Students have to measure thermal flow problems and verify the measurements with detailed simulations. The desired accuracy is 5% or less. The presentation will cover 3 laboratory ... En Savoir Plus

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 ... En Savoir Plus

A Microfluidic System for Capturing Malaria-Infected Blood-Cells Using an Array of Nickel Structures

Pachara Noosawad [1],
[1] Chulalongkorn University, Thailand

Treatment and prevention of malaria, a disease having an anopheles mosquito as a carrier, have become a severe medical issue to many countries in a tropical zone. It was reported that there have been patients about 300-500 millions all over the world[1]. Many countries in South East Asia ... En Savoir Plus

Numerical Analysis of Flow Chamber Morphologies for Pilot-Scale Ultrasonication

Naveen Arunachalam [1],
[1] California Institute of Technology, USA

Ultrasonication effectiveness is an important consideration in the scale-up of lab-scale dispersion experiments. Unlike lab-scale experimentation, which can take advantage of localized tools such as probe and bath sonicators, pilot-scale processes may necessitate the use of large flow ... En Savoir Plus

Boundary Arbitrary Lagrangian-Eulerian and Deformable Boundary Perturbation Method

J. Rivero-Rodriguez [1], B. Scheid [1],
[1] Université Libre de Bruxelles, Brussels, Belgium

Partial differential equations on unknown domains is a mathematical problem that arises in many applications. Several examples can be easily found in the dynamics of free surfaces in fluid dynamics or in fluid-structure interactions. In many situations, large deformations are encountered ... En Savoir Plus

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

Slab dehydration and fluid migration in subduction zone is important because it allows us to understand characteristics of the arc volcanism such as migration of the volcano front as well as the global circulation of water and carbon. To minimize the technical difficulties in the ... En Savoir Plus

磁场对带电纳米孔道中阴阳离子的输运模拟 new

赵金保 [1], 瞿忍婕 [2],

[2] 厦门大学能源学院

全球能源需求的不断增长,以及解决与日俱增的环境污染和气候变化的迫切需求,都在不断地刺激着更有效的能源获取技术。虽然在盐度梯度中发现了可提取的能量,即通过开发自然水生系统来获取蓝色能量(blue energy),但单位面积上的能量功率(~5 W/m2)并不高。为了进一步提高能量转化效率,就不能单纯依靠吉布斯自由能(Gibbs free energy),还应该充分利用磁场。故,探究磁场对带电纳米孔道中阴阳离子输运的影响,来启发实验取得进一步的突破。 应用了AC/DC模块和化学物质传递模块中的稀物质传递,以及对传递属性中的弱表达式进行修改。从而实现磁场 ... En Savoir Plus
