Dependence of the relative variance of the concentration profile at the outlet on Reynolds number and diffusion coefficient.
Variation of Sout on: (a) Re (for n = 51.04k (solid squares) and n = 70.5k (empty squares); reference value: Re = 0.1 (dashed line)) and (b) D (reference value: D = 5 × 10-11 m2/s (dashed line)). Sout and ln(Pe) are reported in black on the left y-axis and in blue on the right y-axis, respectively; (0-SERP).
