Simulating Wear in Disc Brakes

N. H. Elabbasi[1], M. J. Hancock[1], S. B. Brown[1]
[1]Veryst Engineering, LLC., Needham, MA, USA

Wear is a complex phenomenon relevant to many problems involving frictional contact, such as mechanical brakes, seals, metal forming, and orthopedic implants. The rate of wear depends on the properties of the contacting materials and operating conditions. One widely used model of wear is ... En savoir plus

Natural Convection Driven Melting of Phase Change Material: Comparison of Two Methods

D. Groulx[1], F. Samara[1], P.H. Biwole[2]
[1]Department of Mechanical Engineering, Dalhousie University, Halifax, NS, Canada
[2]Department of Mathematics and Interactions, University of Nice Sophia-Antipolis, Nice, France

Design of latent heat energy storage systems (LHESS) requires knowledge of heat transfer processes within them, as well as the phase change behavior of the phase change material (PCM) use. COMSOL Multiphysics can be used to model (LHESS). Natural convection plays a crucial role during ... En savoir plus

Design of a Controlled Dosing Scheme for Liquids using a Venturi

M. Dagaonkar[1], V. Kumaran[1], R. Venkataraghavan[1], D. C. Franklin[1]
[1]Unilever R&D, Bangalore, Karnataka, India

Dosing a predetermined quantity of one liquid into another, in a controlled fashion, is a process often encountered in a variety of operations at both industrial and laboratory scales. This process becomes a challenging one if it has to be carried out in a continuous mode, without using ... En savoir plus

Effects Of Saline Infusion On The Lesion Size During The Radiofrequency Ablation Of Liver Cancer

O. E. Hin [1]
[1] Monash University, Malaysia

In this study, a computational model is developed and solved using COMSOL Multiphysics software to estimate the lesion size during saline-infused RFA. Transport of saline is set up by modifying the Poisson equation and the convection-diffusion equation [3] under the Mathematics module. ... En savoir plus

Modeling Magnetic Configurations for Improved Separations of Magnetic and Non-Magnetic Materials

S. Khushrushahi[1], T.A. Hatton[1], M. Zahn[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

Magnetic separation of magnetic liquid phases/particles from non-magnetic liquid phases/particles are needed for applications such as cleaning up oil spills by separating oil and water liquid phases or separating magnetic materials from non-magnetic materials in biomedical and ... En savoir plus

[1] ESS-Bilbao, Bilbao, Spain

The design of ESS-Bilbao RFQ (RadioFrequency Quadrupole) linear accelerator cavity using COMSOL Multiphysics is presented. The work includes geometry definition, electrostatics, electromagnetic and thermomechanical coupled simulations. The main part of the work corresponds to the ... En savoir plus

The Virtual Aquarium: Simulations of Fish Swimming

M. Curatolo [1], L. Teresi [2],
[1] Department of Engineering, Università Roma Tre, Roma, Italy
[2] Department of Mathematics and Physics, Università Roma Tre, Roma, Italy

Our goal is to reproduce the key features of carangiform swimming by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL Multiphysics software. Fish swimming is an important area of research, with relevant developments on biomechanics, robotics ... En savoir plus

Design and Simulation of Piezoelectric MEMS Cantilever

R. Shah [1], A. Nayak [1], B. D. Pant [2],
[1] Birla Institute of Technology & Science, Pilani, Rajasthan, India
[2] CSIR-Central Electronics Engineering Research Institute, Pilani, Rajasthan, India

Zinc Oxide (ZnO) was chosen as the piezoelectric material. A multi – d31 mode cantilever design was used, with varying dimensions of cantilever, to form an array. The individual cantilevers can be either connected in series or in parallel to achieve different output characteristics. ... En savoir plus

Tunable MEMS Capacitor for RF Applications

H. S. Shriram[1], T. Nimje[1], D. Vakharia[1]
[1]BITS Pilani, Rajasthan, India

Radio Frequency MEMS devices have emerged to overcome the problem of high losses associated with semiconductors at high frequencies. A tunable MEMS capacitor is a micrometre-scale electronic device whose capacitance is controlled through different actuation mechanisms which govern the ... En savoir plus

Single Phase Flow Models in Fractal Porous Media Using a Fractal Continuum Mechanics Approach
