Drag Fluctuations of a Fully Deployed Flow Actuator Embedded Inside Turbulent Boundary Layer Flow

Dr. A. Elzawawy[1]
[1]Engineering & Technology Department, Vaughn College of Aeronautics & Technology, Flushing, NY, USA

Introduction: In this work, a CFD model of 2D flow around a fully deployed flow actuator was developed using COMSOL Multiphysics® software and the CFD Module. The results of COMSOL modeling is also compared with the experimental data of the same dimensions actuator. The 100mmX2mm ... Read More

Convective Cooling of Electronic Components

J. S. Crompton[1], H. Singh[1], K. Koppenhoefer[1]
[1]AltaSim Technologies, LLC, Columbus, OH, USA

In response to continued miniaturization and increased multi-functionality of electronic circuits, the number of integrated circuit (IC) packages on the circuit board continues to increase. As a consequence the operating power density increases and significant increases in the operating ... Read More

Thermal Analysis of Additive Manufacturing

S. Yushanov[1], J. S. Crompton[1], K. C. Koppenhoefer[1]
[1]AltaSim Technologies, LLC., Columbus, OH, USA

This study analyzed the laser powder bed additive manufacturing process. The laser is modeled as a moving heat source with time dependent heat transfer causing local, transient melting of the metal powder. Heat transfer is considered to take place due to convection in the molten metal ... Read More

Thermal-Electrical Study of an Ultra-fast Disconnect Switch with a Piezoelectric Actuator

L. Graber[1], C. Widener[1], S. Smith[1], M. Steurer[1]
[1]Center for Advanced Power Systems (CAPS), Florida State University, Tallahassee, FL, USA

A research team at FSU CAPS is developing a novel fast disconnect switch based on a piezoelectric actuator for use in next-gen electric power distribution systems. COMSOL Multiphysics® software was used to optimize geometry and material selection of the disconnect switch. Current ... Read More

Topology Optimization of Lithium-Ion Battery Electrode Microstructure Morphology for Reduction of Damage Accumulation and Longevity of Battery Life

P. Clarke[1], R. Abedi[1]
[1]University of Tennessee Space Institute, Tullahoma, TN, USA

The ubiquitous commercial use of Lithium-Ion batteries (LIBs) has increased interest in their implementation into efficient energy storage systems for clean and renewable power sources and the electrical transportation industry. Unfortunately, LIBs are not yet technological mature to ... Read More

High Frequency Resonators Using Exotic Nanomaterials

B. Panchapakesan[1], M. Loeian[1]
[1]Department of Mechanical Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

Human made mechanical resonators have been around for a thousand years. Early applications included musical instruments and chronographs operating in millihertz to kilohertz frequencies while more recent interest has turned ultra-high frequency resonators and oscillators suitable for ... Read More

Conductivity Estimation of Breast Cancer Using COMSOL® Modeling of Microwave Scattering and Frechet Mean Estimate of Covariance

A. Jeremic[1], E. Khoshrowshahli[2]
[1]Electrical & Computer Engineering, McMaster University, Hamilton, ON, Canada
[2]Biomedical Engineering, McMaster University, Hamilton, ON, Canada

Breast cancer detection is one of the most important problems in health care and it is second most frequent cancer according to WHO. It is recommended that women over fifty or even younger in some cases do a screening test every two years. Besides clinical breast examination, there are ... Read More

Finite Element Modeling of Conventional and Pulsed Eddy Current Probes for CANDU® Fuel Channel Inspection

M. Luloff[1], J. Morelli[1], T. W. Krause[2]
[1]Department of Physics, Engineering Physics & Astronomy, Queen's University, Kingston, ON, Canada
[2]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada

A pulsed Eddy Current (EC) probe, using the transient response to a stepped voltage is being developed for in-reactor inspection of CANDU® fuel channels. Pulsed EC has the advantage of generating a spectrum of discrete frequencies, allowing the simultaneous collection of data from a ... Read More

Modeling of Hydrogel-Based Controlled Drug Delivery System for Breast Cancer Treatment

K. Cluff[1], L. Saeednia[2], H. Mehraein [1], R. Asmatulu[2]
[1]Department of Bioengineering, Wichita State University, Wichita, KS, USA
[2]Department of Mechanical Engineering, Wichita State University, Wichita, KS, USA

Polymeric hydrogel is a promising class of drug delivery systems with the controlled release behavior in the body. In-situ forming hydrogels can be injected into the body as a fluid which forms a gel within the body tissue and improve the efficacy of the drugs. Various polymers have been ... Read More

Simulation and Experimental Analysis of Drug Release Rates from Magnetic Nanocomposite Spheres

L. Saeeednia[1], H. Mehraein[2], F. Abedin[1], K. Cluff[2], R. Asmatulu[1]
[1]Department of Mechanical Engineering, Wichita State University, Wichita, KS, USA
[2]Department of Bioengineering, Wichita State University, Wichita, KS, USA

Targeted drug delivery systems have been wildly studied in cancer therapy due to the toxicity of most of chemotherapeutic drugs. Nanoparticles can be attached to the small molecules of the drugs and serve as drug carriers to deliver the drug molecules into the area of interest. In this ... Read More
