Steps for the Optimization of Pipe and Tubing Extrusion Dies

J.R. Puentes[1], T.A. Osswald[1], S. Schick[2], J. Berg[2]
[1]Polymer Engineering Center, University of Wisconsin, Madison, WI, USA
[2]TEEL Plastics, Baraboo, WI, USA

The extrusion of polyolefin pipes suffers degradation due to mechanical design problems of the extrusion die that is commonly used. This study uses numerical and computational approaches to detect problematic areas in the die geometry. Simulations show that in the conventional die there ... En savoir plus

Nonstandard High Voltage Electric Insulation Models

T. Christen[1]
[1]ABB, Corporate Research, Zürich, Switzerland

The design of modern electric insulation devices for medium and high voltage (HV) applications requires computational work that goes beyond solving just a Laplace equation for the electric potential, and limiting the electric field below critical values. Both field calculation and ... En savoir plus

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

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

MEMS based Gecko Foot for Micro Robotics

A. Pasumarthy [1], H. Sinha [1], A. Islam [1],
[1] Birla Institute of Technology, Mesra, Ranchi, Jharkhand, India

Gecko foots have inspired researchers to develop designs that can help robots to tread vertically oriented surface. These nanobots find many applications as they can perform a lot of operations more efficiently and also lower the cost of such operations. These can be employed in various ... En savoir plus

Modeling Convection during Melting of a Phase Change Material

D. Groulx, and R. Murray
Mechanical Engineering
Dalhousie University
Halifax, NS
Canada

COMSOL Multiphysics can be used to model a latent heat energy storage system. A 2D numerical study was performed to simulate melting of a PCM including both conduction and convective heat transfer. The heat transfer in fluids and laminar flow physics interfaces were used. To model ... En savoir plus
