Performance of an aerodynamic particle separator

Waste Management, 1996
Abstract This compact, high-flow device aerodynamically separates small particles from a gas stream by a series of annular truncated airfoils. The operating concept, design and performance of this novel particle separator are described. Tests results using corn starch and post-cyclone coal fly ash are presented. Particle collection efficiencies of 90%

Performance of an Aerodynamic Particle Sizer

Applied Occupational and Environmental Hygiene, 1993
Abstract In occupational and ambient environments, there is increasing need to monitor the atmospheres in real time so that emission sources are easily identified and exposure episodes can be better understood. Recently, several instruments have been developed commercially for aerodynamic particle-size measurements.

The aerodynamic performance of paragliders

The Aeronautical Journal, 1999
AbstractAn analysis of paraglider performance has revealed that wing section drag is the most significant contribution to overall drag. Wind tunnel measurements performed on two-dimensional hollow models indicate that intake drag is less significant than previously thought.

Aerodynamic Design and Performance

Aircraft Engineering and Aerospace Technology, 1965
An Outline of the Basic Configuration and Aerodynamic Features of the Argosy including Performance and Flight Handling Qualities. THE basic concept of the Argosy as a medium‐size freighting aircraft with a large capacity fuselage of high cross sectional area and low freight floor defined to a large extent the shape of the aircraft.

Aerodynamic performance of a winggrid [PDF]

Comprehensive experimental and analytical studies have been conducted to assess the integration of a force balance in a low speed wind tunnel and to measure the performance of a new type of aeroplane winglet called a winggrid. The winggrid is an extension to a wing that utilises a cascade of wings to decrease the induced drag on a wing (La Roche, 2005).

Aerodynamic Performance of Biological Airfoils

2nd AIAA Flow Control Conference, 2004
Experimental studies on static, non-flapping dragonfly wings have shown favorable aerodynamic performance at low Reynolds number (Re ≤ 10,000). High lift is hypothesized to arise from the dragonfly’s pleated wing structure. A numerical study of flow past a modeled dragonfly wing section as well as its comparison to a corresponding profiled airfoil and ...

Aerodynamics of High Performance Wing Sails

SNAME 1st Chesapeake Sailing Yacht Symposium, 1974
Some of the primary requirements for the design of wing sails are discussed. In particular, the requirements for maximizing thrust when sailing to windward and tacking down wind are presented. The results of water channel tests on six sail section shapes are also presented.

Continuation of modelling of perforated plate aerodynamics performance

Aerospace Science and Technology, 2002
Summary: This paper continues a physical modelling of a transpiration flow, presented in [\textit{P. P. Doerffer} and \textit{R. Bohning}, Aerosp. Sci. Technol. 4, No.~8, 525--534 (2000; Zbl 0961.76518)], by developing a system of gasdynamic equations for viscous flows in tubes of a perforated plate.

High-performance aerodynamic computations for aerospace applications

Parallel Computing, 2017
A recent study outlining a NASA vision for computational fluid dynamics (CFD) development emphasizes the importance of high-performance computing (HPC) in increasing the impact of CFD on design and certification of aerospace vehicles.Broader use of CFD in aerospace applications has been limited by its inability to accurately predict turbulent separated
