Analysis of Solar Hot Water Storage

K.O. Lund
Applied Chemical and Engineering Systems

In a Solar Hot Water System, the hot water from the solar collector enters at the top of the storage tank. A relevant question concerning the storage is what will the outlet temperature be. In the present work we present a way to model Solar Hot Water Systems.

Mathematical Frame-work for the Productivity Index of Wells with Fast Forchheimer (non-Darcy) Flow in Porous Media

[3] Texas A & M University, Department of Mathematics

In the current paper, similar features for fast or turbulent, non-linear flows subjected to Forchheimer equations are analyzed. Under some hydrodynamic and thermodynamic constrains, it has been shown that there exists the so called pseudo-steady state regime for Forchheimer flows in reservoir media. This invariant is called diffusive capacitance, which is the mathematical model for the well ...

Stability and Bifurcation of Cathode Arc Attachment in AC Operated High-Intensity Discharge Lamps

A. Lenef
Osram Sylvania

High-intensity discharge (HID) lamps are highly-efficient light sources with many applications. Depending on the dimensions of the electrode, lamp current, and waveforms, the plasma may attach to the cathode in a diffuse mode, that covers the electrode tip surface, or a localized mode where heating and current transfer occur in a local region of the electrode surface. The localized mode is ...

Modelling of Catalytic Radiant Heaters

J.P.Mmbaga, T.M. Mannan, N. Joederi, S.E. Wanke, and R.E. Hayes
University of Alberta

In this work we present the modelling of catalytic radiant heaters. The presentation outlines the mathematical model as well as a Laboratory setup of a catalytic radiant heater.

Computer Modelling of Deformable non-Newtonian Flow using COMSOL Multiphysics

H.A. Lecuyer[1], F.H. Bertrand[1], P.A. Tanguy[1], J.P. Mmbaga[2], and R.E. Hayes[2]
[1] Ecole Polytechnique , Montreal
[2] University of Alberta, Edmonton

This presentation is concerned with the modelling of deformable non-Newtonian Flow using COMSOL Multiphysics. This general modelling approach has more concrete applications such as paper coating in a metering size press, meniscus location by PIDS to mention a few.

Mathematical Modeling of Blood Flow in the Presence of Atherosclerosis

T. Gadkari, and A. Jeremic
McMaster University, ON, Canada

Atherosclerosis affects the arterial blood vessels causing stenosis in the arteries because of which the artery hardens resulting in loss of elasticity in the affected region. In this paper, we present an approach to model the pulsating flow of blood through such an atherosclerosis affected region of the artery using the finite element method. We further discuss the statistical model used to ...

High-Performance Multiphysics Simulations

M. Ringh
COMSOL AB

In this presentation we present where COMSOL Multiphysics and its modules will be in the year 2007. The presentation considers the upcoming features, not only from a developers point of view, but also through examples from different branches of applied physics and mathematics. In addition, we present some important milestones during the past 10 years for COMSOL ...
