Failure Mode Classification for Life Prediction Modeling of Solid-State Lighting
(2015-07-24)
Since the passing of the Energy Independence and Security Act of 2007, the U.S. government has mandated greater energy independence which has acted as a catalyst for accelerating and facilitating research efforts toward ...
Liquid Jet Impingement with Spent Flow Management for Power Electronics Cooling
(2015-07-21)
The high levels of heat generated by power electronics, on board electric and hybrid-electric vehicles, require the use of aggressive liquid cooling techniques. Incorporating the electronics cooling into the radiator flow ...
Multiphase Numerical Simulations of Dielectric Fluid Immersion Cooling Scenarios including Effects of Nucleation Site Density and Bubble Departure Diameter Functions
(2015-07-24)
Multiphase numerical simulations have typically been restricted to a few standard functions for key boiling parameters. In this study, ANSYS Fluent was used to model dielectric fluid immersion cooling of multichip modules ...
Estimation of State of Charge (SOC) and Water Loss for Absorbed Glass Mat Lead Acid Battery
(2015-07-29)
Accurate and fast estimation of state of charge (SOC) and water loss during battery operations plays an important role in the prevention of over-charge and over-discharge and optimal control strategy of charging, which ...
Thermal Conductivity Enhancment of Solid Eicosane-Based Silver Nanostructure-Enhanced Phase Change Materials for Thermal Energy Storage
(2015-07-29)
In this thesis, thermal conductivity of eicosane-based PCM was enhanced by suspending highly-conductive silver nanoparticles resulting in the formation of nanoparticle-enhanced PCM (NePCM). Eicosane (C20H42) was selected ...
Experimental Investigation of a Liquid Immersion Cooled Electronics Module using Two-Phase Heat Transfer for Thermal Management
(2015-09-25)
As society’s demand for constant connectivity to one another grows, both from an economic and social perspective, the requirements on high performance data centers throughout the world will as well. The expeditious transfer ...
Online Monitoring of State of Health for AGM Lead Acid Batteries
(2015-07-29)
Prediction of degradation states like power and capacity fade is the most challenging issue for rechargeable batteries, which is called State of Health (SOH). Power and capacity fade is evaluated by predicting Available ...
Design and Implementation of a SoC-Based Real-Time Vector Tracking GPS Receiver
(2015-05-06)
