Gasification is a thermochemical pathway used to convert carbonaceous feedstock into syngas (CO and H2) in a deprived oxygen environment. The process can accommodate conventional feedstock such as coal, discarded waste including plastics, rubber, and mixed waste owing to the high reactor temperature (1000 °C-1600 °C). Pyrolysis is another conversion(More)
Annual wind data at Masdar City (24.4202°N, 54.6132°E) has been recorded in attempt to assess wind energy potential. Collected records are analyzed for the development of wind predicting models, which can be used in conjunction with different wind turbine power curves. Thereby, accurate wind energy production can be assessed for a given(More)
For decision makers and researchers working in a technical domain, understanding the state of their area of interest is of the highest importance. For this reason, we consider in this chapter, a novel framework for Web-based technology forecasting using bibliometrics (i.e. the analysis of information from trends and patterns of scientific publications). The(More)
Gasification is making a strong comeback as a sustainable energy source in clean energy systems such as IGCC, as a renewable source utilizing millions of tons of waste dumped in the landfill, and as a solution to the ground water leaching and CO<sub>2</sub> &amp; CH<sub>4</sub> emission that risking our ecological system. In this paper, thermodynamic(More)

-Waste to Energy can be pursued biologically, chemically, or thermally, leading to the production of chemicals of high caloric value or sensible heat. The petroleum industry has been generating an alarming amount of solid waste in the form of oily sludge. It is a hazardous of complex emulsion of various petroleum hydrocarbons (PHCs), solid particles, water(More)
The focus of most low wind turbine designers is how to maximize power extraction. Designing horizontal axis turbine for relatively low average wind speed requires power extraction at high tip speed ratio obtained at high angle of attack. These high angles occur at low Reynolds numbers which makes it even more difficult to generate sufficient lift to turn(More)
The efficiency of the wind power conversion systems can be significantly improved by the judicious choice of the control algorithm. To maximize the power extraction of a Doubly-Fed Induction Generator (DFIG) based wind turbine, we propose a non-linear control algorithm, based on a sliding mode theory. It has been used to control the wind turbine speed so(More)
Biodiesel is a powerful alternative fuel that is less polluting and problematic to produce and implement. The production process of biodiesel also gives us the byproduct glycerol, which is a useful feedstock to produce hydrogen and syngas as fuels. With such high value as a fuel we are in need of better production technologies for biodiesel, which is(More)
This work presents estimates of time histories of pressure coefficients at several taps on the roof of a 1/200 model of a 200 x 100 x 20 ft low-rise building with a 1/24 slope gable roof building. The estimates were obtained using a large eddy simulation (LES). The first and second moments as well as peaks for the time histories are compared with those(More)
Gasification is a thermochemical pathways used to convert carbonaceous feedstock into syngas (CO and H2) in deprived oxygen environment. The process can accommodate conventional feedstock such as coal as well as discarded waste including plastics, rubber, and even MSW due to the high reactor temperature of 1000 to 1600oC. Pyrolysis is another conversion(More)
