[2]IRPI-CNR, Strada delle Cacce, Torino, Italy

This study investigates the feedback between fault slip and dike intrusions during the Mono-Inyo eruption sequence of ~1350 A.D. (Mono Basin, California). We perform an extensive validation of 3D finite element models, implemented in the Structural Mechanics module of COMSOL Multiphysics, against standard analytical solutions of fault dislocation in a homogeneous elastic flat halfspace. The ...

Universidad Politecnica de Valencia, Valencia, Spain

Brine disposal from desalination plants placed in inland areas far from sea is an important problem. Evaporation ponds can be used for reducing the waste to solid state but they require huge amounts of land. Evaporation using arrays of wet surfaces can minimize the land requirements. One characteristic of the methods based on natural evaporation is the uncertainty associated to the influent ...

Air Flow Characteristics Inside an Industrial Wood Pallet Drying Kiln

A-G. Ghiaus, M-A. Istrate, and A-M. Georgescu
Technical University of Civil Egineering, Bucharest, Romania

Analysis and optimization of air flow distribution inside drying kiln systems contribute to the improvement of the final product quality. The present study reports on the threedimensional numerical solution of air flow within a drying kiln enclosure. The air flow field is examined in different configurations and operation conditions. Depending on the off/on switched fans, we obtain various air ...

Comparative Study of an Open Waveguide.Application to Deconvolution of a Magnetic Probe in Near-Field Zone

A. Saghir, J.W. Tao, and C. Avram
INP, Laplace site Enseeiht, Toulouse, France

We present here our work on deconvolution of a magnetic probe to mesure electromagnetic emissions in near-field zone. To achieve this work,we have chosen a rectangular waveguide (WR90) as a radiating structure.Theoritical near-field is simulated using a FEM software (COMSOL) and also obtained by using a program based on transverse operator method (TOM), that lead to a very good field ...

Numerical Implementation Of A Multivariable Thermomechanical Model For Unsaturated Bentonite

V-M. Pulkkanen, and M. Olin
VTT Technical Research Centre of Finland, Espoo, Finland

A compacted bentonite clay buffer is planned to be used as a part of the engineered barrier system in the KBS-3 concept for the disposal of spent nuclear fuel. Simulations together with experimental studies are needed to ensure that bentonite fulfills its safety functions in the concept. In this paper, one type of bentonite model, namely a thermomechanical model developed by Jussila, is ...

Transport Phenomena of Bubbles in a High Viscous Fluid

F. Pigeonneau
CNRS/Saint-Gobain, France

Dr. Franck Pigeonneau is currently working in the joint laboratory between the Centre National de la Recherche Scientifique (CNRS) and the company Saint-Gobain. He received his Ph. D. in 1998 from the University Pierre et Marie Curie (Paris, France). His main research activities are devoted to the transport phenomena in high viscous fluids relevant for glass melting processes. He is using COMSOL ...

An Elastic and Hyperelastic Material Model of Joint Cartilage - Calculation of the Pressure Dependent Modulus of Elasticity by Comparison with Experiments and Simulations

T. Reuter, and M. Hoffmann
fzmb GmbH
Research Centre of Medical Technology and Biotechnology
Bad Langensalza, Germany

In this paper we introduce a elastic and hyperelastic model to describe the biomechanics of joint cartilage. As biomechanical property we calculated the pressure dependent E-modulus E = f(s) to describe the dependence of the biomechanical properties on pressure. The calculation based on the comparison and the iterative approach of the force-way-functions between the experiments and ...

An Elastic and Hyperelastic Material Model of Joint Cartilage - Calculation of the Pressure Dependent Material Stress in Joint Cartilage

T. Reuter, and M. Hoffmann
fzmb GmbH
Research Centre of Medical Technology and Biotechnology
Bad Langensalza, Germany

In this paper we introduce a elastic and hyperelastic model to describe the pressure dependent material stress in joint cartilage. We used the pressure dependent E-modulus E = f(s) to calculate the material stress. E = f(s) is a degree 4 polynomial . The indentor was pressed 0.4 mm into the tissue. The results show that the maximal stress at the contact zone between indentor and cartilage ...

Computational Fluid Dynamics Simulations of an Innovative System of Wind Power Generation

S. Carcangiu, A. Fanni, and A. Montisci
Department of Electric and Electronic Engineering
University of Cagliari
Cagliari, Italy

In this work an innovative wind power generation in urban areas is proposed. The generation system substitutes the roof of the building and it consists of a static part, the stator, and a moving part, called impeller, which is a centripetal turbine with vertical axis of rotation. Since the objective is to conveying the air flow in the stator, the logarithmic spiral has been chosen as the shape ...

Advanced Application of an Automated Generative Tool for MEMS Based on COMSOL Multiphysics

F. Bolognini
University of Cambridge
Cambridge, UK

This work presents a different use of COMSOL as an integrated component of a computational tool framework used to automate designs creation. CNS-Burst is a computational synthesis method that has been implemented with the aim of automatically generating solutions to an assigned design task. COMSOL is integrated in the method and used to evaluate the performance of the design solutions found. ...
