Analysis of Low-Speed Unsteady Airfoil Flows
This book provides an introduction to unsteady aerodynamics with emphasis on the analysis and computation of inviscid and viscous two-dimensional flows over airfoils at low speeds. It begins with a discussion of the physics of unsteady flows and an explanation of lift and thrust generation, airfoil flutter, gust response and dynamic stall. This is followed by an exposition of the four major calculation methods in currents use, namely inviscid-panel, boundary-layer, viscous-inviscid interaction and Navier-Stokes methods. Undergraduate and graduate students, teachers, scientists and engineers concerned with aeronautical, hydronautical and mechanical engineering problems will gain understanding of the physics of unsteady low-speed flows and an ability to analyze these flows with modern computational methods.

An economic feasibility study of extracting electrical energy from solar panels
The research is a case that study depends on both secondary and primary data. Secondary data should be collected from the firms producing the photo panels(local and foreign) and those that working in this field in addition to the data of the ministry of electricity in Syria and the national center of power, while primary data should be collected by interviews with the persons working in electricity field .Then the traditional steps of commercial profitability analysis should be followed starting in pre-feasibility study passing the detailed feasibility study steps which, in turn, consists of the following phases : market study , technical study , financial study in order to reach the estimated net cash flows that should be used in analyzing the project feasibility depending on all criteria both traditional " payback-period . Simple rate of return" and economic criteria " net present value and the internal rate of return”.
Ambiguities in Decision-oriented Life Cycle Inventories: The Role of Mental Models and Values
Shows for the first time how mental models and values influence this attribution in the life cycle inventory step of LCA. One of the key findings is that the different management rules for a sustainable use of materials must be taken into account for the attribution of material and energy flows to a product. Otherwise, improvement options recommended by an LCA might turn out to even worsen the environmental situation if reassessed from a meta-perspective. As a consequence of this book, the claim of unambiguitiy (‘objectivity’) of the life cycle inventory must be abandoned. A group-model building process for LCA is developed that allows one to grasp the decision makers' mental models and values in the inventory analysis on a case- and situation-specific basis. Only by this, LCA results will become relevant in a decision-making process. Two case studies on the modelling of recycling and other end-of-life options of aluminium windows and beech wood railway sleepers in LCA complement the methodological part.

Air-Ice-Ocean Interaction : Turbulent Ocean Boundary Layer Exchange Processes
At a time when the polar regions are undergoing rapid and unprecedented change, understanding exchanges of momentum, heat and salt at the ice-ocean interface is critical for realistically predicting the future state of sea ice. By offering a measurement platform largely unaffected by surface waves, drifting sea ice provides a unique laboratory for studying aspects of geophysical boundary layer flows that are extremely difficult to measure elsewhere. This book draws on both extensive observations and theoretical principles to develop a concise description of the impact of stress, rotation, and buoyancy on the turbulence scales that control exchanges between the atmosphere and underlying ocean when sea ice is present. Several interesting and unique observational data sets are used to illustrate different aspects of ice-ocean interaction ranging from the impact of salt on melting in the Greenland Sea marginal ice zone, to how nonlinearities in the equation of state for seawater affect mixing in the Weddell Sea.
Air quality in airplane cabins and similar enclosed spaces
The editor of this volume invited a wide range of experts to provide an in-depth treatment of virtually all aspects of aircraft cabin air quality. The topics are covered at a level comprehensible to all who fly as well as being of sufficient depth to be informative to decision makers concerned with purchase, design, operation, and servicing of passenger aircraft. Topics are grouped under: Control of Aircraft Cabin Air Quality; Possible Effects of Low Humidity, Decreased Outside Air Flows; and Effects of Some Aircraft Malfunctions on Cabin Air Quality. The volume concludes with Air Quality Systems for Related Enclosed Spaces, in which chapters cover air quality in buildings, ships, submarines, and spacecraft, which provide novel approaches potentially applicable to aircraft.
