Reduction of Fluid Forces on a Square Cylinder Using Passive Control Methods
COMSOL Multiphysics® is used in this study to simulate the flow around a square cylinder and focus on reducing the forces on the cylinder by passive control methods. Numerical simulations are made to find optimum cases of control methods that guarantee maximum reduction for Reynolds ... Read More
Application of Kelvin's Inversion Theorem to the Solution of Laplace's Equation Over a Domain That Includes the Unbounded Exterior of a Sphere
In simulating physical systems modeled as solutions of partial differential equations over an unbounded domain, a challenge arises owing to the impossibility to cover an unbounded domain with a mesh. A classical problem in fluid dynamics, a solid sphere of radius a_s is submerged in a ... Read More
Two-Dimensional Thermal Hydraulic Analysis and Benchmark in Support of HFIR LEU Conversion using COMSOL
The research documented herein was funded by a research contract between the Research Reactors Division (RRD) of Oak Ridge National Laboratory (ORNL) and the University of Tennessee, Knoxville (UTK) Mechanical, Aerospace and Biomedical Engineering Department (MABE). The research was ... Read More
A Method for Efficient Calculation of Diffusion and Reactions of Lipophilic Compounds in Complex Cell Geometry
A general description of effects of toxic compounds in mammalian cells is facing several problems. Firstly, most toxic compounds are hydrophobic and partition phenomena strongly influence their behaviour. Secondly, cells display considerable heterogeneity regarding the presence, activity ...

Possibility of Implicit LES for Two-Dimensional Incompressible Lid-Driven Cavity Flow Based on COMSOL Multiphysics
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
Analysis of RF Characteristics of a Compound Semiconductor Device Integrated with a Wide-Band Antenna for THz Wireless Communications
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
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
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
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
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
