柔性压阻传感器微结构设计

王宗荣 [1], 王珊 [1], 牛韶玉 [1], 李谷尧 [1], 李皓盛 [1],
[1] 浙江大学

The development of highly sensitive and stretchable pressure sensors is an emerging technological goal to realize the accurate real-time measurement of signals in a living body for health monitoring and medical applications. Designing various microstructures of PDMS film, such as micro ... Read More

TDS-based porous flow modeling in subduction zone

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 ... Read More

Benchmarking as Key Element of Confidence Building in Safety Assessments for Radioactive Waste Disposal

E. Weetjens
SCK-CEN (the Belgian Nuclear Research Centre), Mol, Belgium

Verification of the codes applied for assessment of the long-term repository safety is typically one of the quality assurance requirements demanded by regulatory bodies, in the disposal of radioactive waste. In this paper, an internationally organized benchmark exercise is presented, in ... Read More

Magnetic Particle Buildup Growth on Single Wire in High Gradient Magnetic Separation  

F. Chen
Department of Chemical Engineering, M.I.T., Cambridge, MA, USA

Magnetic fluids containing nano or submicron magnetic particles and their application in food, biological and pharmaceutical systems have recently attracted increasing attention. Magnetic particles can be collected efficiently in magnetizable matrices (e.g. iron wires) in high gradient ... Read More

Electro Magnetic Wave Simulation in Fusion Plasmas

O. Meneghini[1], and S. Shiraiwa[1]
[1]Plasma Science and Fusion Center, Massachusetts Institute of Technology, Massachusetts, USA

Fusion is a form of nuclear energy which has impressive advantages from the point of view of fuel reserves, environmental impact and safety. If successful, fusion energy would ensure a safe, resource conserving, environmentally friendly power supply for future generations. In a world ... Read More

An All-Purpose Full-Vectorial Finite Element Model for Arbitrarily Shaped Crossed-Gratings

G. Demésy[1], F. Zolla[1], A. Nicolet[1], and M. Commandré[1]
[1]Institut Fresnel, Université Aix-Marseille III, École Centrale de Marseille, France

We demonstrate the accuracy of the Finite Element Method (FEM) to characterize an arbitrarily shaped crossed-grating in a multilayered stack illuminated by an arbitrarily polarized plane wave under oblique incidence. To our knowledge, this is the first time that 3D diffraction ... Read More

Evaluation of COMSOL as a Tool for Pinpointing Moisture Entering Locations From Inside Surface Moisture

J. van Schijndel
Eindhoven University of Technology, Eindhoven, Netherlands

The location and nature of the moisture leakages are sometimes difficult to detect. Moreover, the relation between observed inside surface moisture patterns and where the moisture enters the construction is often not clear. The objective of this paper is to investigate inverse modeling ... Read More

The Effect of Cartilaginous Rings on Deposition by Convection, Brownian Diffusion and Electrostatics

H. Akerstedt
Luleå University of Technology, Luleå, Sweden

This paper presents a numerical study of the deposition of spherical charged nanoparticles caused by convection and Brownian diffusion in a pipe with a cartilaginous ring structure. The model is supposed to describe deposition of charged particles in the upper generations of the ... Read More

Thermal Characterization of a Chemical Reactor Coupling COMSOL and ModeFrontier

N. Pacheco[1], D. Pavone[1], K. Surla[1], E. Schaer[2], and J. Houzelot[2]
[1]IFP-Lyon, France
[2]LRGP-ENSIC, France

For Hydrogen production purpose from bio-ethanol, IFP set up a pilot reactor that can work at high temperature (1000°C) and high pressure (20 bar). Experiments show that this reactor has a specific thermal behavior that should be modeled in addition to chemical and hydrodynamics to ... Read More

Blistering of Industrial Floors on Concrete Substrate: The Role of Air Overpressure
