Abstract

The results of measuring the probability density of the temperature fluctuations in a weakly heated submerged turbulent jet are given for the range of Reynolds numbers extending from 7.7·103 to 5·105. It is shown that for large positive fluctuations the probability density is independent of the Reynolds number and is formed by bursts with a characteristic length of the order of the integral scale.
