Gaskinetic Modeling On Dilute Gaseous Plume Impingement Flows, Chunpei Cai Dec 2016

Gaskinetic Modeling On Dilute Gaseous Plume Impingement Flows, Chunpei Cai

Michigan Tech Publications

This paper briefly reviews recent work on gaseous plume impingement flows. As the major part of this paper, also included are new comprehensive studies on high-speed, collisionless, gaseous, circular jet impinging on a three-dimensional, inclined, diffuse or specular flat plate. Gaskinetic theories are adopted to study the problems, and several crucial geometry-location and velocity-direction relations are used. The final complete results include impingement surface properties such as pressure, shear stress, and heat flux. From these surface properties, averaged coefficients of pressure, friction, heat flux, moment over the entire flat plate, and the distance from the moment center to the flat …

Mitigation Of The Impact Of High Plug-In Electric Vehicle Penetration On Residential Distribution Grid Using Smart Charging Strategies, Chong Cao, Luting Wang, Bo Chen Dec 2016

Mitigation Of The Impact Of High Plug-In Electric Vehicle Penetration On Residential Distribution Grid Using Smart Charging Strategies, Chong Cao, Luting Wang, Bo Chen

Michigan Tech Publications

Vehicle electrification presents a great opportunity to reduce transportation greenhouse gas emissions. The greater use of plug-in electric vehicles (PEVs), however, puts stress on local distribution networks. This paper presents an optimal PEV charging control method integrated with utility demand response (DR) signals to mitigate the impact of PEV charging to several aspects of a grid, including load surge, distribution accumulative voltage deviation, and transformer aging. To build a realistic PEV charging load model, the results of National Household Travel Survey (NHTS) have been analyzed and a stochastic PEV charging model has been defined based on survey results. The residential …

Two-Temperature Dual-Phase-Lags Theory In A Thermoelastic Solid Half-Space Due To An Inclined Load, Ashraf M. Zenkour, Ahmed E. Abouelregal, Khaled A. Alnefaie, Nidal H. Abu-Hamdeh, Abdulmalik A. Aljinaidi, Elias C. Aifantis Aug 2016

Two-Temperature Dual-Phase-Lags Theory In A Thermoelastic Solid Half-Space Due To An Inclined Load, Ashraf M. Zenkour, Ahmed E. Abouelregal, Khaled A. Alnefaie, Nidal H. Abu-Hamdeh, Abdulmalik A. Aljinaidi, Elias C. Aifantis

Michigan Tech Publications

This article addresses the thermoelastic interaction due to inclined load on a homogeneous isotropic half-space in context of two-temperature generalized theory of thermoelasticity with dual-phase-lags. It is assumed that the inclined load is a linear combination of both normal and tangential loads. The governing equations are solved by using the normal mode analysis. The variations of the displacement, stress, conductive temperature, and thermodynamic temperature distributions with the horizontal distance have been shown graphically. Results of some earlier workers have also been deduced from the present investigation as special cases. Some comparisons are graphically presented to estimate the effects of the …

Improving Automated Global Detection Of Volcanic So2 Plumes Using The Ozone Monitoring Instrument (Omi), Verity Flower, Thomas Oommen, Simon Carn Jul 2016

Improving Automated Global Detection Of Volcanic So2 Plumes Using The Ozone Monitoring Instrument (Omi), Verity Flower, Thomas Oommen, Simon Carn

Michigan Tech Publications

Volcanic eruptions pose an ever-present threat to human populations around the globe, but many active volcanoes remain poorly monitored. In regions where ground-based monitoring is present the effects of volcanic eruptions can be moderated through observational alerts to both local populations and service providers such as air traffic control. However, in regions where volcano monitoring is limited satellite-based remote sensing provides a global data source that can be utilized to provide near real time identification of volcanic activity. This paper details the development of an automated volcanic plume detection method utilizing daily, global observations of sulphur dioxide (SO2) by the …

Exergy Study On The Effect Of Material Parameters And Operating Conditions On The Anode Diffusion Polarization Of The Sofc, Khalid Zouhri, Seong Young Lee Jun 2016

Exergy Study On The Effect Of Material Parameters And Operating Conditions On The Anode Diffusion Polarization Of The Sofc, Khalid Zouhri, Seong Young Lee

Michigan Tech Publications

In the presented work, a model is created in order to investigate the effect of different material parameters and operating conditions on the anode diffusion overpotential, which influence the exergy and energy efficiency of the solid oxide fuel cell (SOFC). In this research, it was demonstrated that the anode material parameters and operating conditions of the device components such as porosity, tortuosity, pore diameter, temperature, pressure and current density of the anode have various effects on the anode diffusion overpotential, which consequently affect the exergy and energy efficiency of the SOFC. The model has provided a strong direction on how …

Review Of Sensing Methodologies For Estimation Of Combustion Metrics, Libin Jia, Jeffrey D. Naber, Jason R. Blough Jan 2016

Review Of Sensing Methodologies For Estimation Of Combustion Metrics, Libin Jia, Jeffrey D. Naber, Jason R. Blough

Michigan Tech Publications

For reduction of engine-out emissions and improvement of fuel economy, closed-loop control of the combustion process has been explored and documented by many researchers. In the closed-loop control, the engine control parameters are optimized according to the estimated instantaneous combustion metrics provided by the combustion sensing process. Combustion sensing process is primarily composed of two aspects: combustion response signal acquisition and response signal processing. As a number of different signals have been employed as the response signal and the signal processing techniques can be different, this paper did a review work concerning the two aspects: combustion response signals and signal …
