Calculation of Capacitances of Symmetrical Triple Coupled CPW Transmission Lines and Multilayer CPW Broadside Coupled Lines Balun

S. Musa[1], M. N. O. Sadiku[1]
[1]Prairie View A&M University, Prairie View, TX, USA

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, the quasi-TEM analyses of symmetrical triple coupled ... Mehr lesen

Modeling the Effect of Porosity on the Elastic Properties of Synthetic Graphite Using CT Scans and the Finite Element Method

G. Sowa[1], R. Paul[1], R. Smith[1]
[1]GrafTech International Inc., Parma, OH, USA

Predicting the physical properties and performance of carbon and graphite materials based on the microstructure of the finished material is a challenging endeavor. This paper discusses the process and workflow for measuring and analyzing the pore structure of graphite by combining ... Mehr lesen

SD Numerical Simulation Technique for Hydrodynamic Flow Gas-Solids Mixing

I. Mantilla[1], S. De Vicente[2]
[1]National University of Engineering, Lima, Perú
[2]Polytechnic University of Madrid, Madrid, Spain

We formulate a new mathematical model of gas-solids mixing hydrodynamic flow [1] in a combustion chamber with a fluid bed system used in the combustion of mineral coal waste. This model in study is called Model Gas-Solids Mixing and it is constructed by averaging the conservation ... Mehr lesen

Application of COMSOL Multiphysics® Pipe Flow Module to Develop a High Flux Isotope Reactor (HFIR) System Loop Model

P. K. Jain[1], D. Wang[1], J. D. Freels[1]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA

Oak Ridge National Laboratory’s High Flux Isotope Reactor (HFIR) is the highest flux reactor-based source of neutrons for research in the United States. Thermal and cold neutrons produced by HFIR are used to study physics, chemistry, material science, engineering, and biology. Currently, ... Mehr lesen

Inductive Conductivity Measurement of Seawater

R. W. Pryor[1]
[1]Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

The conductivity of seawater directly correlates with the concentration of dissolved salts. This model demonstrates a new approach to the methodology of inductive conductivity measurement of seawater and other liquids. COMSOL Multiphysics® was used to build a parametrically swept model ...

Design of a Microreactor for Microwave Organic Synthesis through Microwave Heating Simulations

W. H. Lee[1], K. Jensen[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

We will present the issues of a microreactor setup designed for microwave organic synthesis and demonstrate how COMSOL Multiphysics® is used to understand the mechanism of microwave heating and improve the microreactor design. The RF Module was used for the electromagnetics and solid ... Mehr lesen

Quench Propagation and Detection in a YBCO Racetrack

G. Escamez[1], C. Lorin[1], T. Wu[1], P. J. Masson[1]
[1]University of Houston, Houston, TX, USA

High temperature superconductors (HTS) such as YBCO coated conductors show great promise for future applications where high magnetic fields are needed. The superconducting state only exists under a critical surface defined in the (J,T,B) space. Quench is the process by which a current ... Mehr lesen

Modeling 3D Calcium Waves from Stochastic Calcium Sparks in a Sarcomere Using COMSOL Multiphysics®

L. T. Izu[1], Z. Coulibaly[2], B. Peercy[2]
[1]University of California-Davis, Davis, CA, USA
[2]University of Maryland, Catonsville, MD, USA

This paper utilizes the COMSOL Multiphysics® general form PDE interface and MATLAB® to model stochastic calcium waves in a sarcomere (basic unit of a heart cell). The model we present here shows the evolution of waves generated from calcium being released stochastically from sites ... Mehr lesen

Optimization of Mechanical Properties of Superconducting Cavities for Project X LINAC

I. Gonin[1], M. Awida[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermilab, Batavia, IL, USA

Project X is a proposed proton accelerator complex at Fermilab. The CW LINAC is based on five types of resonators operating at three frequencies: half-wave, spoke, and elliptical. The low beam current for the CW operation of Project X requires cavities to operate at a high loaded Q and, ... Mehr lesen

Phase Field Modeling of Helium Precipitate Networks on Solid-state Interfaces

D. Yuryev[1], M. Demkowicz [1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

We describe simulations performed in COMSOL Multiphysics® of the precipitation of helium (He) on solid-state interfaces. The non-uniform precipitation of He at certain interfaces is a result of a heterogeneous energy distribution in the interface plane: He wets high interface energy ( ... Mehr lesen
