- Аннотация: Statistical properties of a turbulent flow have been investigated experimentally in a shock tube with a turbulence grid. The fluctuations of the refractive index were detected with the aid of a laser-schlieren technique. It was found that the structure function Dn(r) has the form: Dn(r)=c(1-exp(-br)sin(ar)/(ar)),a,b,c being constants, in contrast with Kolmogorov's two-thirds law. These data were used in order to determine the PSF and MTF. Numerical results for the image of an object in a turbulent flow are also presented. Date: 20 March 2003 ISBN: 9780819446664
