Multifractal Model of Atmospheric Turbulence Applied to Elastic Lidar Data

Lidar system applied in atmospheric pollution monitoring.

A lidar system, incorporating tunable dye lasers and a 25-cm diam Newtonian telescope, has been constructed and applied in atmospheric pollution monitoring. The system, which is fully controlled by a specially designed microcomputer, has been used in several field tests, where stack effluents as well as the ambient air have been monitored. Results from particle, NO(2), and SO(2) measurements ar...

Quantifying the Effects of Atmospheric Stability on the Multifractal Spectrum of Turbulence

Over the past decade, several studies suggested possible analogy between price dynamics in the foreign exchange market and atmospheric turbulent flows. Such analogies suggest that applications in business and industry can directly benefit from detailed quantification of the scale-hierarchy existing in fully developed turbulent flows. Numerous studies have already demonstrated the multifractal p...

Recent Turbulence Model Advances Applied to Multielement Airfoil Computations

A one-equation linear turbulence model and a two-equation nonlinear explicit algebraic stress model (EASM) are applied to the ow over a multielement airfoil. The e ect of the K-" and K-! forms of the two-equation model are explored, and the K-" form is shown to be de cient in the wallbounded regions of adverse pressure gradient ows. A new K-! form of EASM is introduced. Nonlinear terms present ...
