Numerical Modeling of Single-Phase Fluid-Flow in Wavy Micro-Channels

R. Durantes1, J. Moon1, A. Pacheco-Vega1, J. Rafael Pacheco2
1Department of Mechanical Engineering, California State University, Los Angeles, Los Angeles, USA
2SAP America Inc., Tempe, AZ,, USA

High power-density electronic devices had achieved levels of heat generation that have exceed the current heat removal capacities. Due to the increase in power density of modern electronic chips, there is a need of a higher heat flux removal capabilities, and single-phase fluid-flow wavy ... Read More

A Reduced Order Model of Lithium Ion Batteries Derived from the Cahn-Hilliard Equation

R. Painter1, I. Embry1, L. Sharpe2, S. K. Hargrove2
1Department of Civil Engineering, Tennessee State University, Nashville, TN, USA
2Department of Mechanical Engineering, Tennessee State University, Nashville, TN, USA

Emerging battery technologies are addressing applications of renewable and fossil fuel energy sources since they can store and release energy on demand. In recent years significant strides have been made in lithium battery technology. Lithium batteries are the primary sources of power in ... Read More

Electrochemistry Modeling of a Smartphone Based Electrochemiluminescence Sensor

H. Kwon1, E. C. Rivera2
1Andrews University, Berrien Springs, MI, USA
2Laboratório Nacional de Ciência e tecnologia do Bioetanol, Campinas, SP, Brazil

An electrochemiluminescence (ECL) sensor was developed in a smartphone-based platform using a disposable disk-shaped carbon electrode. A time-varying square waveform potential was applied to the working electrode, and the current and ECL intensity data were measured. The applied ... Read More

Change of Chemical Species with Progress of Crevice Corrosion

L. Tong1, M. Yamamoto2
1Keisoku Engineering System Co., Ltd., 1-9-5 Uchikanda, Chiyoda-ku, Tokyo 101-0047, Japan
2Japan Atomic Energy Agency, Fukoku Seimei Bldg. 19F, 2-2-2 Uchisaiwaicho, Chiyoda-ku, Tokyo 100- 8577, Japan

One of the most destructive modes of corrosion of metals is localized corrosion. This can take many forms depending on the chemical and electrochemical environment of the metal. One important form is crevice corrosion, which occurs where two or more surfaces in close proximity lead to ... Read More

Real-Time Prediction of Incipient Failure in Working Fluids

R. W. Pryor, Ph.D.1
1Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

Working fluids (engine oil, transmission fluid, hydraulic fluid, coolants, etc.) become contaminated in use. To ensure that the equipment is not damaged by the contaminated fluid, the fluid is typically removed and replaced periodically. For large groups of machines, the used fluid is ... Read More

Modeling Interplay Between Catalyst Performance and Microenvironment in CO2 Electrolyzers

D. Raciti1, T. Braun1, T. Moffat1, H. Xu2, M. Cruz2, B. Wiley2
1National Institute of Standards and Technology, Gaithersburg, MD USA
2Department of Chemistry, Duke University, Durham, NC, USA

With the anticipated effects of global climate change upon us, induced by egregious CO2 emissions, it is imperative to implement technologies to close the carbon cycle. One potential technique to do this is storing the energy from intermittent sources (e.g. solar, wind, hydro) in the ... Read More

Optimizing Three-Dimensional Microelectrode Geometries for Neurostimulation

L. van de Panne1, K. Haider1, T. Lijnse1, C. Dalton1
1University of Calgary, Calgary, Alberta, Canada

Neuromodulation, a closed-loop therapy that combines the recording and stimulation of neurons using implanted electrodes, is widely considered the future of care for many neurological diseases including epilepsy and Parkinson’s. Existing neuromodulation therapies, however, are limited by ... Read More

Simulation of Drying Process During Fabrication of Lithium-Ion Battery Porous Electrode

S. R.[1], N. S. T.[1]
[1]CSIR-Central Electrochemical Research Institute, India

Lithium ion battery electrodes are porous composite film made up of two or three different types of solid material. Typically using the fabrication of the electrode, the solid powders (active material, binder and in most cases a conductive active) are dispersed in a solvent like NMP and ... Read More

Membraneless Soluble Lead Redox Flow Cell at Low to High External Flow Rates

M. Ansari[1], S. Kumar[1]
[1]Indian Institute of Science, Bangalore, India

Renewable energy sources such as solar and wind are intermittent in nature. Their effective utilization requires efficient, low cost energy storage systems to complement energy harnessing systems. The rechargeable flow batteries have emerged as the most suitable candidates due to their ... Read More

Electrical Stress in High Voltage Capacitor Units
