Query: On the intermittency exponent of the turbulent energy cascade   We consider the turbulent energy dissipation from one-dimensional records in
experiments using air and gaseous helium at cryogenic temperatures, and obtain
the intermittency exponent via the two-point correlation function of the energy
dissipation. The air data are obtained in a number of flows in a wind tunnel
and the atmospheric boundary layer at a height of about 35 m above the ground.
The helium data correspond to the centerline of a jet exhausting into a
container. The air data on the intermittency exponent are consistent with each
other and with a trend that increases with the Taylor microscale Reynolds
number, R_\lambda, of up to about 1000 and saturates thereafter. On the other
hand, the helium data cluster around a constant value at nearly all R_\lambda,
this being about half of the asymptotic value for the air data. Some possible
explanation is offered for this anomaly.
