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 ...

Applied Multiphysics in Thermoresistive and Magnetoresistive Sensor Models

R.W. Pryor
Pryor Knowledge Systems, Inc.
COMSOL, Certified Partner

Efficient, effective, and functional operation of autonomous systems requires a comprehensive real-time understanding, by those systems, of the embedding environment. This paper presents a brief overview of the multiphysics considerations involved in the development of models for thermoresistive and magnetoresistive sensors systems.

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 ...

Constructal Design of Concurrent Power Distribution Networks

[2] Department of Mechanical Engineering and Center for Advanced Power Systems, Florida State University

This paper reports a strategy to design a network of higher immunity and capacity of recovery to faults or other destructive events. The capacity of survivorship and recovery increases when the system possesses some redundancy, and this means sources and lines and switching capability that are able to take over areas that loose connectivity to their parent source. Therefore, a second network, ...

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 ...

Effects of Nonlinear Magnetic Properties on Magnetic Bonding Forces for Magnet Array Self-Assembly

S.B. Shetye, J.S. Agashe, and D.P. Arnold
University of Florida

The objective of this researh is to develop new, magnetically-directed, self-assembly approaches to enable three-dimensional structures to be formed in parallel from a heterogeneous mixture of parts of arbitrary size and shape.

Activation Imaging of the Heart using Diffusion Models

R. Abou-Marie, and A. Jeremic
McMaster University, Canada

The inverse problem of electrocardiography involves determining information about the electrical activity of the heart from measurements on the body surface. The estimation of certain physiological parameters can potentially improve early detection of heart disease. In this study, we present an algorithm for estimating parameters that characterize the electrical activation. Estimation of ...
