Possibility of Implicit LES for Two-Dimensional Incompressible Lid-Driven Cavity Flow Based on COMSOL Multiphysics

M. Hashiguchi[1]
[1]Keisoku Engineering System Co., Ltd. Chiyoda-ku, Tokyo, Japan

In the present paper, possibility of implicit large eddy simulation(LES) by using the laminar flow interface of COMSOL Multiphysics Ver.4.3a, has been examined for two-dimensional lid-driven cavity flow with the Reynolds number up to 1,000,000. The flow computations with time-dependent ... Read More

[1]Tokyo Metropolitan University, Hachioji City, Tokyo, Japan

Use of the terahertz(THz) region, which is unexplored frequency band, is investigated and expected for the next-generation high-speed wireless communication. In this presentation, we propose a monolithic integrated device by using mesa-shaped compound semiconductor and a thin-metal ... Read More

Effect of Fluid Conditions on Air-Liquid Interface in Hydrophobic Micro Textured Surface

S. Takahashi[1], S. Ogata[1]
[1]Tokyo Metropolitan University Hachioji City, Tokyo, Japan

We studied the influence of a number of gas-liquid interface on the drag reduction effect by numeric simulation. Level set method was used for an analysis of gas-liquid interface. The analytic model is rectangular channel of height h = 5 micrometer and width w = 20 micrometer with two ... Read More

Numerical and Experimental Evaluation for Measurement of a Single Red Blood Cell Deformability Using a Microchannel and Electric Sensors

K. Tatsumi[1]
[1]Kyoto University, Kyoto City, Kyoto, Japan

An electric micro-resistance sensor that can continuously measure the deformability of a single red blood cell (RBC) in a microchannel and a numerical model that can simulate the resistance and capacitance of the cell membrane and cytoplasm are developed and improved. The resistance ... Read More

Toward an Evaluation of the Tonal Colouring of the Japanese koto using COMSOL Multiphysics and Acoustics Module

K. Coaldrake[1]
[1]The University of Adelaide, Adelaide City, South Australia, Australia

This paper investigates the potential for a multidisciplinary approach using COMSOL Multiphysics for the evaluation of the tonal colouring of the Japanese koto (13-stringed zither). It uses Ando’s classic acoustic studies (1986; 1996) as a benchmark for the analysis of the natural ... Read More

Study of Tertiary Current Distributions on the Wafer in a Plating Cell

L. Tong[1]
[1]Keisoku Engineering System Co., Ltd,. Chiyoda-ku, Tokyo, Japan

The reciprocating paddle cell is a known practical method for depositing alloy films on wafer substrates. Recently, the mass transfer boundary layer within an industrial wafer plating cell was studied based on the measurement of limiting current. It was indicated that a shear-plate fluid ... Read More

Investigation of Blade Profiles of Vertical Axis Wind Turbine by Numerical Simulation

S. Yoshioka[1]
[1]Ritsumeikan University, Kusatsu City, Shiga, Japan

There are two types of vertical axis wind turbine, drag-type and lift-type. Drag type wind turbine can rotate in low speed wind condition, although its rotation speed is low. Lift type wind turbine can rotate at higher speed, although it works only in high speed wind condition. This ... Read More

Design of Microfluidic Device for Cellular Experiment Under Controlled Oxygen Tension

K. Funamoto[1], I.K. Zervantonakis[2], R.D. Kamm[2]
[1]Tohoku University, Sendai City, Miyagi, Japan
[2]Massachusetts Institute of Technology

Numerical simulation of oxygen tension was performed to develop a microfluidic device for three-dimensional real-time observation of cellular response under hypoxia. The optimal experimental condition was obtained through investigations of effects of parameters, such as device thickness ... Read More

Dynamic Electromagnetic Analysis of Guitar Pickup Aided by COMSOL Multiphysics

T. Furukawa[1], H. Tanaka[2], H. Itoh[1], H. Fukumoto[1], M. Ohchi[2]
[1]Saga University, Saga City, Saga, Japan
[2]Chiba Institute of Technology

In transient analyses of electromagnetic fields with moving media, it is difficult to grasp the phenomena theoretically in the same manner of the convective heat diffusion since the treatment of the coupled problem with the field and dynamics must be necessary. In this presentation, we ... Read More
