Abstract
A technique to measure turbulent vorticity flux was developed and meas urements were carried out of vorticity flux components u(i)OMEGA(j) an d corresponding crosspectra, as well as crosspectra between vorticity OMEGA(i) and temperature T. The highest correlation was found between u3 and OMEGA2, their spectral correlation coefficient r in the frequen cy range 0.01-1 cps exceeded 0.6. Rather high was the correlation betw een u1 and OMEGA2 (0.3 < r < 0.5). Similarly are correlated OMEGA2 and T. Pairs of components u3 and OMEGA1, u2 and OMEGA3 were found to be almost uncorrelated. The results obtained have been compared with some theoretical predictions.
