Some theoretical aspects of the turbulent point-spread function

Journal of the Optical Society of America A, 2007
In a previous work [J. Opt. Soc. Am. A24, 753 (2007)], we developed a theory describing the space-time statistics of the scintillation and displacement fields of the turbulent point-spread function (PSF), which we validated using imaging data. We now expand on that work by deriving the theoretical expression for the spread fields of the PSF.

The spread of turbulent flames confined in ducts

Symposium (International) on Combustion, 1967
Theoretical predictions have been made of the shape of, and velocity distribution in, turbulent flames spreading symmetrically across steady streams of pre-mixed combustible gas, confined within ducts formed by two plane walls. The predictions are based on the hypothesis that the gas burns as soon as it is entrained into the region of turbulent shear ...

Beam spreading of vortex beams propagating in turbulent atmosphere

Applied Optics, 2012
We present some results obtained by numerical modeling of the propagation of vortex beams LG(0l) through a randomly inhomogeneous medium. The vortex beams are the lower order Laguerre-Gaussian modes. Such beams, if propagated under conditions of weak turbulence, also experience distortions, like a Gaussian beam.

Simple Expressions for the Spread of Turbulent Jets

Aeronautical Quarterly, 1967
SummarySimple expressions are derived for predicting the spread of turbulent jets issuing into parallel moving airstreams. Difficulties with applying these expressions to practical problems are discussed and comparisons with experimental results are given.
