Abstract

Correlation functions were used for investigating the turbulent energy dissipation and for obtaining the intermittency exponents. Air and gaseous helium were used at cryogenic temperatures. In a wind tunnel the air data were obtained in a number of flows and the atmospheric boundary layer at a height of 35 m above the ground. The air data increased with the Taylor microscale Reynolds number whereas the helium data clustered at a value that was about half of the asymptotic value for the air data.
