Phys. Rev. Lett. 91, 075001 (2003) [4 pages]Effect of Mean Flow Shear on Cross Phase and Transport ReconsideredReceived 29 March 2003; published 11 August 2003 We reconsider the important question of the effect of a strong mean shear flow on the transport of a passive scalar field. By incorporating the effect of resonance, we show that the flux scales with the mean shear Ω as Ω-1. The results also indicate that the scaling of the flux and cross phase with shear is rather weak and that the cross phase is not always more heavily suppressed than the amplitude of the turbulence. Furthermore, we show that the scalings of flux and cross phase with Ω depend on the statistics of the turbulent flow. © 2003 The American Physical Society URL:
