湍流的高度
The present invention relates to controlled airflow and air distribution within a laboratory safety enclosure and in particular, to turbulence-free airflow within a laboratory fume hood. The fume hood of the present invention has a work chamber and an access opening having an upper edge. A ...
anyone who has flown on an aircraft has probably gone through turbulence, that disturbing jolting and shaking ranging from mildly unpleasant to quite terrifying. passenger to passenger, the sensation of turbulence can differ greatly; some hardly notice it while others feel great discomfort or even an...

Comment on "Turbulence-free ghost imaging" [Appl. Phys. Lett. 98, 111115 (2011)] Jeffrey H. Shapiro Full-Text Cite this paper Add to My Lib Abstract: It is shown that lensless pseudothermal ghost imaging is not immune to spatial resolution loss from the presence of atmospheric turbulenc...
On the basis of Prandtl’s semiempirical theory it may be assumed that A = ρl2|dv̄/dy|, where the mixing length l is the turbulence analogue of the molecular mean free path. Similarity hypotheses (seeSIMILARITY THEORY) play a major role in the semiempirical theories. In particular, ...
