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.

High-Performance Multiphysics Simulations

M. Ringh

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 ...

Numerical Modeling of EM Pump Efficiency

D.P. Cook, Y. Chen, H.Chen, and J. Ma
University of Nevada, Las Vegas

The pilot Molte lead-bismuth target circuit (TC-1) in the University of Nevada was designed for beam power of 1 MW accelerator driven system (ADS). Circulation of the liquid alloy is driven by an annular linear induction pump. A numerical study of the pump efficiency has been conducted to determine which operational parameters are responsible for this low efficiency and to give insight ...

Vibrational Analysis using Wavelet Techniques coupled with Wing Structural Modeling of the Pathfinder Plus

C. Smith, and C.M. Akujuobi
Center of Excellence for Communication Systems Technology Research, Texas

The motivation for this work is to explore the combination of a multiphysics COMSOL model of the wing of the Pathfinder Plus research aircraft with a wavelet-based vibration detection scheme. COMSOL Multiphysics is utilized to model the physics of the aerodynamics that produce vibration in the wing structure of the Pathfinder Plus. Next, three Daubechies wavelets are used to detect the ...

Chemical Pulse Dynamics and Control in Microdesigned Catalysts: Phenomena, Modeling and Computational Wrappers

L. Qiao, and I.G. Kevrekidis
Department of Chemical Engineering, Princeton University

We study the effect of two-dimensional composite catalyst geometry and spatiotemporal laser heating on the dynamics of CO oxidation on a Pt (110) surface. The project involves a combination of modeling, computation and experimentation. We show (through both FEMLAB and specially designed experiments) that local laser heating actuation appropriately designed in space and time can be critical in ...

3D Temperature Distribution during Self-Propogating High-Temperature Synthesis of Advanced Ceramics

I. Selig[1], S. Lin[1], D.L. Cocke[1], and D. Luss[2]
[1] Lamar University
[2] University of Houston

Self-propagating High-temperature Synthesis (SHS) is an economical process to produce quality advanced ceramics. In this work, SHS of solid oxide fuel (SOFC) cathode materials was modeled using COMSOL Multiphysics.

Influence of COMSOL on the Design and Testing of the High Flux Isotope Reactor HB-4 Cold Source: Validation of the Simulation

J. D. Freels
Oak Ridge National Laboratory

This presentation concerns our numerical and experimental research on the High Flux Isotope Reactor HFIR, located at the Oak Ridge National Laboratory. In this presentation we give a Brief Pictorial Introduction to the HFIR, som physical properties of Supercritical Hydrogen, and Simulations of both natural and forced convection problems using COMSOL Multiphysics. This presentation also ...
