Design Geometry Optimization of Vertical Cracks in Thermal Barrier Coatings from Simulated Thermal and Mechanical Behavior

C. Heveran[1], J. Xu[1], D. Cole[2], S. Basu[1], V. Sarin[1]
[1]Division of Materials Science and Engineering, Boston University, Brookline, MA, USA
[2]Department of Mechanical Engineering, Boston University, Brookline, MA, USA

Turbine blades are coated with thermal barrier coatings (TBCs) to reduce operating temperature. TBCs experience stress from coefficient of thermal expansion mismatch with the bond-coat and substrate. Vertical cracks are thought to offer stress relief, but influence of crack geometry on ... Mehr lesen

Design of a Pressure Sensor to Monitor Teeth Grinding

I.M. Abdel-Motaleb[1], K. Ravanasa[1], K.J. Soderholm[2]
[1]Department of Electrical Engineering, Northern Illinois University, DeKalb, IL, USA
[2]Department of Restorative Dental Sciences, College of Dentistry, University of Florida, Gainesville, FL USA

Studying teeth grinding behavior and other oral conditions requires the ability to accurately measure the pressure on the teeth. Placing a sensor in the mouth requires small size devices with powering and measurement techniques that do not hinder the normal life of the patient. To meet ... Mehr lesen

Aggregation Kinetics of Colloidal Nanoparticles in a Circulating Microfluidic Cavity

M.R. Barmi[1], B.D. Piorek[1], M. Moskovits[2], C.D. Meinhart[1]
[1]Department of Mechanical Engineering, University of California Santa Barbara, Santa Barbara, CA, USA
[2]Department of Chemistry and Biochemistry, University of California Santa Barbara, Santa Barbara, CA, USA

Pressure-driven air flow is directed over the microfluidic cavity induces circulating fluid motion in the cavity. Analyte contained in the air stream is absorbed into the cavity, mixes with the nanoparticles as a result of the circulating cavity flow. Therefore, the nanoparticles ... Mehr lesen

Analysis and Design of Antennas for an Implantable Medical Device System for Functional Electrical Stimulation

H. Suri[1]
[1]Alfred Mann Foundation for Scientific Research, Valencia, CA, USA

This poster outlines the results of finite element analyses to study the antenna radiation pattern of an implanted medical device. Also presented are simulation results used to design an electrically small antenna for a portable control unit that communicates with the implants over the ... Mehr lesen

Modeling Electric Fields in Slit Capillary Array Fluidic Actuators with Complex Electrode Geometries

J. Frey[1], A. Droitcour[1], D. Laser[1]
[1]Wave 80 Biosciences, San Francisco, CA, USA

With their small size, low manufacturing cost, fast transient response, and capacity to generate fluid power directly from small electrical power sources, microdevices incorporating electroosmostic flow (EOF) have wide-ranging applications, including newly developed high-performance ... Mehr lesen

Numerical Optimization Technique for the Optimal Design of the Surface Plasmon Grating Coupler

C. Caiseda[1], V. Aksyuk[2], I. Griva[3]
[1]Inter American University of Puerto Rico, Bayamon, PR, USA
[2]National Institute of Standards and Technology, Gaithersburg, MD, USA
[3]George Mason University, Fairfax, VA, USA

The optimal design of the grating coupler for surface plasmon generation is revisited for its interdisciplinary importance in the efficient use of energy, and the strong dependence of the energy convergence rate of the system on the design. This work contributes a comprehensive gradient ... Mehr lesen

Modeling of DC Discharges in Argon at Low Pressures

V. Gorokhovsky[1]
[1]Vapor Technologies, Inc., Longmont, CO, USA

The glow discharges in argon at pressures of 1 to 20 mTorr are modeling using COMSOL Plasma Module. DC glow discharge with secondary electron emission is compared to low pressure arc with thermionic emission. Boundary conditions on dielectric discharge tube walls are compared to that of ...

Two Dimensional Blood Shear Modeling in a Blood Cooling Catheter

R. Sikorski[1], B. Chapman[1], T. Merrill[1]
[1]Rowan University, Glassboro, NJ, USA

A CFD cardiac catheter model was developed to determine the potential for blood hemolysis during administration of local therapeutic hypothermia using a CoolGuide catheter. In vivo animal studies have shown that mild hypothermia may reduce reperfusion injury often associated with heart ... Mehr lesen

3-Dimensional Blood Cooling Model inside a Carotid Bifurcation

R. Sikorski[1], T. Merrill[1]
[1]Rowan University, Glassboro, NJ, USA

Stroke is caused by an interruption of brain blood supply and is one of the leading causes of death and disability. A mild reduction of 2-5°C in tissue temperature through hypothermia has shown reduced tissue infarct size, increased tissue recovery, and positive neurological effects. ... Mehr lesen

Wind Flow Modeling of Area Surrounding the Case Western Reserve University Wind Turbine

M. Fernandes[1], D. Matthiesen[1]
[1]Case Western Reserve University, Cleveland, OH, USA

The CWRU Turbine is a research turbine located in a urban campus in Cleveland, Ohio. This location may create turbulence, resulting in a possible loss in energy generation. This research attempts to answers the question of whether the wind flow is affected by the buildings or not. The ... Mehr lesen
