Application of Numerical Simulation in Geotechnical Engineering

Dr. Meen-Wah Gui[1]
[1]Department of Civil Engineering, National Taipei University of Technology, Taipei, Taiwan

In this work, COMSOL Multiphysics was used to develop a model to investigate the degree of saturation in sloped terrain. The model was validated via laboratory experiments incorporating Lan’s man-made rainfall slope model test. The validated model was used in an actual case study to simulate the Maokong Landslide.

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 resonant frequencies and design of the sounding body of the koto. It reports on the development of the model and ...

A Study on Estimation of Permittivity Distribution using a Genetic Algorithm and COMSOL® Java API

[1]Kazuyoshi TOMIYAMA et al.

Chiba Institute of Technology, Narashino, Chiba, Japan[1]

The numerical model can be dynamically modified and analyzed by using the COMSOL Java API. We estimated the relative permittivity, diameter and position of the dielectric in a experiment device based on the electric potential and the capacitance of experimental results. The estimation method was developed by the COMSOL Java API and Genetic Algorithm. In this presentation, we will introduce a ...

Effect of Interfacial Charge on the Drop Deformation under the Application of Oscillatory Electric Field.

R. Patil[1], and V. A. Juvekar[1]
[1] Department of Chemical Engineering, Indian Institute of Technology Bombay, Maharashtra

Study of interaction of drops and bubbles with electric field is important for understanding the physics involved in various physical phenomenas and industrial processes. Important applications arise in colloidal systems (Miller and Scriven, 1970), meteorology and cloud physics (Sartor, 1969), electrostatic spraying of liquids (Balachandran and Bailey, 1981), power engineering applications ...

Numerical Simulation of Heart Valve Motion and Fluid Structure Interaction

Tijerino Monge, T., Carmona Infante, V.
Costa Rica

This model studies a portion of the vascular system of a normal person, in particular the left ventricle and the mitral valve of the heart. The flowing blood applies pressure to the ventricle before, after and specially during the contraction process of the heart, thereby deforming the structure.

A Model of SuperRens Effect to Describe Future Generation Optical Data Storage

Gidon, S., Hyot, B., Poupinet, L.
CEA Grenoble Leti

In the quest for a higher data storage capacity, different solutions for the future generations of optical discs (after the Blu-ray format, BD) are under investigations. An increase of the NA beyond 0.85 (NA of the BD format) requires the use of near field optics with all the difficulties inherent to those techniques (fine control of the distance between the optical head and the media). Today ...

Thermo-mechanical Behavior of Multilayers

Bilotsky, Y., Gasik, M.
Laboratory of Materials Processing and Powder Metallurgy, HUT, Finland

The model for study of thermal mechanical behavior of multilayer thin films was developed. The stress-strain analysis was carried out in combination with thermal effects. The 2D thinfilm model has been solved by FEMLAB 3.1i. The middle layer was thermally loaded with Ohmic heating and other layer’s thicknesses were varied in time. All material data like elastic coefficients, thermal ...

Prediction of the Effective Thermal Conductivity of Composites with Spherical Particles of Higher Thermal Conductivity than the one of the Polymer Matrix

Filip, C., Garnier, B., Danes, F.
Laboratoire de Thermocinétique de Nantes, UMR

The introduction of conductive filler in polymer matrix is an effective way to increase the thermal conductivity of the plastic materials as needed by several industrial applications. The design of composites requires to optimize heat transfer while taking into account mechanical, ecological concerns and this involves a lot of experimental work. The prediction of the effective conductivity of ...
