Modeling Conventional Swing of a Cricket Ball

R. Latchman [1], A. Pooransingh [1],
[1] University of the West Indies - St. Augustine, St. Augustine, Trinidad and Tobago

Conventional swing is one phenomenon which a bowler uses to gain an advantage over the batsman. This study involved simulating conventional swing in the CFD Module of COMSOL Multiphysics® software and comparing the simulated results with experimental results of previous researchers. The ...

Analysis of Burning Candle

J.S. Crompton, L.T. Gritter, S.Y. Yushanov, and K.C. Koppenhoefer
AltaSim Technologies LLC, Columbus, OH, USA

Analysis of burning candles is extremely complex; combustion produces a highly non-linear temperature profile through the flame in which local temperatures may exceed 1400 °C. Heat transfer includes radiation, conduction and convection components and the low melting point of the candle ... En savoir plus

A Study on Hydrodynamics of Melt Expulsion in Pulsed Nd: YAG Laser Drilling of Titanium

S. Sharma [1], Y. Pachuary [2], S. N. Akhtar [3], J. Ramkumar [1],
[1] Indian Institute of Technology Kanpur, Kanpur, India
[2] Indian Institute of Information Technology, Design and Manufacturing, Jabalpur, India
[3] Integral University, Lucknow, India

Laser drilling of titanium and its alloys is widely used in aerospace industry, as it offers selective removal of material at high accuracy and speed. However, laser drilling often inherits defects such as large heat affected zone, micro cracks and recast layer. These defects depend upon ... En savoir plus

Exergy Analysis of Polymer Flooding in Clastic Reservoirs

A. Hassan [1], H. Bruining [2], T. Musa [3], R. Farajzadeh [2],
[1] Delft University of Technology, Delft, The Netherlands, and Sudan University of Science and Technology, Khartoum, Sudan
[2] Delft University of Technology, Delft, The Netherlands
[3] Sudan University of Science and Technology, Khartoum, Sudan

Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosified water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three ... En savoir plus

Benchmark Model: Natural Convection of Water-Aluminum Oxide Nanofluids in a Square Cavity

M. Z. Saghir [1], A. Ahadi [1], A. A. Mohamad [2],
[1] Department of Mechanical Engineering, Ryerson University, Toronto, ON, Canada
[2] Department of Mechanical Engineering, University of Calgary, Calgary, AB, Canada

Nanofluids is a new class of fluid consisting of particles in a liquid. Different base liquid has been proposed and the most common one is water. The concentration of these particles can range from 0.1% to 5% or greater. Different numerical models have been proposed to solve this ... En savoir plus

Numerical Investigation of Electrolyte Flow in a Multi-Cathode System for Electrochemical Machining

M. Penzel [1], I. Schaarschmidt [1], M. Hackert-Oschätzchen [1], A. Schubert [1],
[1] Professorship Micromanufacturing Technology, Chemnitz University of Technology, Chemnitz, Germany

Manufacturing and finishing of components with complex internal features is a significant challenge. Industrial sectors like automotive industry, aeronautics or medical technology require these internal features with highest precision and repeatability. Such components are often machined ...

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

Application of COMSOL Multiphysics® Software in Transport Phenomena Educational Processes

P. L. Mills [1], M. Vasilev [1], P. Sharma [1],
[1] Department of Chemical and Natural Gas Engineering, Texas A&M University - Kingsville, Kingsville, TX, USA

Introduction Use of simulation software for solving realistic engineering problems has grown significantly in recent years due to the availability of less expensive but more powerful computers and development of user-friendly yet robust codes. From an educational perspective, students in ... En savoir plus

Time Dependent Dirac Equation FEM Solutions for Relativistic Quantum Mechanics

A. J. Kalinowski [1],
[1] Consultant, East Lyme, CT, USA

The paper illustrates the use of COMSOL (via the “Coefficient-Form PDE” option) for obtaining the relativistic quantum mechanics wave function Ψm(x,y,z,t), m=1,4 as a solution to the time dependent Dirac equations. Once having Ψm(x,y,z,t), it can be used to compute the probability ... En savoir plus
