A generalized form of Yaglom's equation, in which the effect of turbulent production of temperature fluctuations is taken into account, is derived. The modified Yaglom equation (which extends the work of Danaila et al. [J. Fluid Mech. 391, 359 (1999)] to incorporate the effects of decay and production) is compared with experimental data. The flow under(More)
Higher-order passive scalar (temperature) structure functions are measured in the turbulent wake of a circular cylinder at a Taylor-microscale Reynolds number (Rlambda) of 370. The scalar is injected by two different means: (i) heating of the cylinder and (ii) use of a mandoline. Even though the second-order statistics (e.g., power spectra, second-order(More)
