Windbreak Effects Within Infinite Wind Farms
Building upon a recent study that showed windbreaks to be effective in increasing the power output of a wind turbine, the potential of windbreaks in a large wind farm is explored using simplified formulations. A top-down boundary layer approach is combined with methods of estimating both the roughness effects of windbreaks and the induced inviscid speed-up for nearby turbines to investigate pow...
متن کاملLarge-eddy Simulation of Windbreak Flow
A large-eddy simulation has been performed of turbulent flow around multiple windbreaks set within a wheat canopy under neutral stability conditions. The simulation is validated against a wind tunnel data set taken under similar conditions. Velocity profiles and second-order statistics are presented and compared to those found in the wind tunnel. From the numerical simulation, we discuss spatia...
متن کاملChallenges and Prospects of European Railways
In the present paper, challenges and prospects of the European railways, along with a proposal for a new strategy policy and specific measures are presented. The declining course of European railways concerning traffic and revenues is first analyzed. Conditions to introduce intra - modal competition are surveyed, among them separation of infrastructure fro...
متن کاملRoads, railways, and childhood cancers.
STUDY OBJECTIVES To locate geographical sources of engine exhaust emissions in Great Britain and to link them with the birth addresses of children dying from cancer. To estimate the cancer initiating roles of nearby roads and railways and to measure effective ranges. DESIGN Birth and death addresses of all children born between 1955 and 1980 in Great Britain, and dying from leukaemia or other...
متن کاملRailways and materials: synergetic progress
Railways were originally uniquely identified with the material of their initial construction and now are technically identified by the characteristic contact of ‘steel wheel on steel rail’. Over 160 years ago failures of iron railway axles led to research into what we now know as metal fatigue. Accidents throughout the ages have acted as catalysts for research and improvements: this lecture wil...
