Wind tunnel testing using reduced scale topography models is a mature technique [1] that enables the investigation of various aspects of wind flows from pollutant dispersion [2] to wind field modifications [3] affected by terrain. Alternatively, or in conjunction with a wind tunnel study, a rigorously developed computational technique would have the potential to provide additional and useful in...

Information $ow predicates are properties of sets of traces and therefore cannot be handled under the Alpern-Schneider framework and the Abadi-Lnmport Composition Principle. McLean proposed a theory in iMCL941 to investigate the composition properties of these predicates and derived a partial order on them. In this paper we present an alternate framework based on many-sorted predicate logic for...

The objective of obtaining a spatially standardized steady stream of air across and along the test section of a wind tunnel has been considered by several researchers. When a wind tunnel is manufactured or montage or move to another position, the study about variation of pressure, Mach number, density and temperature distribution, the variation of pitch and yaw components of flow angularity, bo...

In this present era , a fair transmission pricing scheme is an important issue due to incresed deregulation and restructuring of power sector. In this view, issue of tracing the flow of electricity has been gain importance as its solution helps in evaluating a fair and transparent tariff.An electricity tracing method would make it possible to charge the generators and/or consumers on the basis ...

The Doppler tracing is a sensitive method for depicting movement of the heart wall, valves, and blood flow. This communication reports the authors' experience with the Doppler method in normal persons and patients with various cardiac arrhythmias. Three main components are recognized in the Doppler tracing: the presystolic component, a; component v, due to systolic movement of the ventricles; a...

This paper presents a novel probabilistic optimization algorithm for simultaneous active and reactive power dispatch in power systems with significant wind power integration. Two types of load and wind-speed uncertainties have been assumed that follow normal and Weibull distributions, respectively. A PV bus model for wind turbines and the wake effect for correlated wind speed are used to achiev...

First it will be shown that an actuator disk operating in wind turbine mode extracts more energy from the fluid than can be transferred into useful energy. At the Lanchester-Betz limit the decrease of the kinetic energy in the wind is converted by 2/3 into useful power and by 1/3 into heat. Behind the wind turbine the outer flow and the flow that has passed the actuator disk will mix. In this p...

By a systematic method we construct general classes of exact and selfconsistent axisymmetric MHD solutions describing flows which originate at the near environment of a central gravitating astrophysical object. The unifying scheme contains two large groups of exact MHD outflow models, (I) meridionally self-similar ones with spherical critical surfaces and (II) radially self-similar models with ...

Application of high-precision non-intrusive flow field measurement techniques in transonic cryogenic wind tunnels (CWT) is confined to the lack suitable tracer particles. The present study explored feasibility utilizing non-equilibrium condensing nitrogen droplets as A numerical model condensation was established. Accordingly, process and analysis tracing were investigated. results reveal that ...

This study addresses the energetics of the Southern Ocean, in response to high-frequency wind forcing. A constant-density, multi-layer model is forced with a band of stochastically varying wind stress. The focus is on the interplay between the surface layer and the interior circulation. In line with previous examinations, it is concluded that the interior ocean is not directly energized by the ...
