Solar chimneys (or solar updraft towers) offer an attractive way to use solar energy for production of baseload power. In a power plant of this type, sunshine heats the air under a wide greenhouse-like roofed collector surrounding the central base of a tall chimney. The heated air drives an updraft flow through the tower, whose energy is harvested with turbines. For a sufficiently large plant of this type, the thermal mass of the heated ground under the collector is sufficient to drive the flow even when the sun is down. The primary challenge in building the solar chimney power plant …

Evaluation Of On-Board Photovoltaic Modules Options For Electric Vehicles, Mahmoud M. Abdelhamid Aug 2014

Evaluation Of On-Board Photovoltaic Modules Options For Electric Vehicles, Mahmoud M. Abdelhamid

Mahmoud M Abdelhamid

This paper presents an overview of different commercial photovoltaic (PV) module options to power on-board electric vehicles (EVs). We propose the evaluation factors, constraints, and the decision-making criteria necessary to assess the suitability of this PV module for this application. The incorporation of quality function deployment (QFD) and the analytical hierarchy process (AHP) is the decision-making methodology used in this study. Our approach is innovative and robust in that the evaluation depends upon data collected from PV manufactures datasheets. Unlike traditional research, a hybrid AHP and QFD innovative decision-making methodology has been created, and current commercial PV market data for …

Modeled Impacts Of Cover Crops And Vegetative Barriers On Corn Stover Availability And Soil Quality, Ian J. Bonner, David J. Muth Jr., Joshua B. Koch, Douglas L. Karlen May 2014

Modeled Impacts Of Cover Crops And Vegetative Barriers On Corn Stover Availability And Soil Quality, Ian J. Bonner, David J. Muth Jr., Joshua B. Koch, Douglas L. Karlen

Douglas L Karlen

Environmentally benign, economically viable, and socially acceptable agronomic strategies are needed to launch a sustainable lignocellulosic biofuel industry. Our objective was to demonstrate a landscape planning process that can ensure adequate supplies of corn (Zea mays L.) stover feedstock while protecting and improving soil quality. The Landscape Environmental Assessment Framework (LEAF) was used to develop land use strategies that were then scaled up for five U.S. Corn Belt states (Nebraska, Iowa, Illinois, Indiana, and Minnesota) to illustrate the impact that could be achieved. Our results show an annual sustainable stover supply of 194 million Mg without exceeding soil erosion T …

     The aim of this investigation is to verify and validate the modeling of fluid mechanics and heat transfer processes in a solar chimney power plant. The modeling uses a finite volume method applied to simulate the fluid flow and solve Navier-Stokes equations for the two- dimensional models of the plant. The representative size of the plant can be very large, and turbulence must be accounted for. Several turbulence models were applied in the model. The upstream velocity and power generated by the power plant system was calculated from the CFD results and compared with experimental results and available …
