On The Directional Response of Multi-Driver Column Loudspeaker Configurations Using FEA and BEM

R. Balistreri [1],
[1] Klipsch Group, Inc, Indianapolis, IN, USA

Column Loudspeakers employ multiple drivers to get close to a radiating line source. A line source gives several acoustic advantages versus a point source, especially in highly reverberant environments. This property particularly has made column loudspeakers the preferred solution in ... Read More

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 ... Read More

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 ... Read More

Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®

T. Preney [1], P. Namy [1], J. Wheeler [1]
[1] SIMTEC, Grenoble, France

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... Read More

The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery packs temperature distributions is ... Read More

Comparison of Industrial Agitation for Batch Reacting Vessel Mixing in Bioethanol Fermentation

H. Rana [1],
[1] Loughborough University, United Kingdom

This paper presents the investigation into the phenomena during batch reactor vessel mixing comparing agitation equipment; the Rushton turbine and the Marine propeller; in the production of bioethanol by yeast fermentation. The key factors addressed in selecting equipment were fluid ... Read More

Understanding Ferrofluid Spin-Up Flows in Rotating Uniform Magnetic Fields

S. Khushrushahi, and M. Zahn
Massachusetts Institute of Technology, Cambridge, MA, USA

A fully filled sphere of ferrofluid has constant demagnetizing factors in all three Cartesian directions such that when subjected to a uniform external rotating magnetic field the internal field is also uniform, and ultrasound measurements give no observable flow. Non-uniform magnetic ... Read More
