Assume that experimental studies of turbulent-jet methane-air diffusion flames have been performed under the following sets of conditions of jet exit diameter D and average jet exit velocity U:

For each experiment, estimate at the duct exit and at the position of the maximum average rate of heat release:

(a) the turbulence Reynolds number based on the integral scale,

(b) the average rate of dissipation of turbulent kinetic energy,

(c) the Kolmogorov microscale,

(d) the Taylor microscale,

(e) the Kolmogorov time, and

(f) the time for convection of a fluid element over a Kolmogorov scale in the laboratory frame.
