Mean concentrations and concentration fluctuations in a stirred‐tank reactor

Abstract

Mixing has a major influence on the product ratio of fast competiti®e reactions, as the product ratio of these reactions is

Fluctuating fast chemical reactions in a batch process modelled by stochastic differential equations

“…This approach is consistent with the experimental work of Verschuren et al [23], who plotted the statistical properties of a tracer concentration probability distribution function in a tank reactor with respect to the stirrer speed. The mixing volume fluctuations were investigated using fluorescein as a tracer, whose local mean concentration and concentration variance were measured using planar laser-induced fluorescence (PLIF).…”

Large‐scale oscillations of a feedstream inside a stirred tank reactor

“…These PLIF and LDV experiments are Ž . described in a previous article Verschuren et al, 2002 . The geometry of the vessel and some additional PLIF data processing is described below.…”

Planar Laser-Induced Fluorescence Method for Analysis of Mixing in Laminar Flows

“…[1][2][3][4] The vast majority of the studies involving dye concentration measurements in stirred tanks using LIF have been restricted to turbulent flows. 5,6 While turbulence is often desired in mixing operations (due to its unsteady velocity fields and nonlinear inertial forces), it is not always feasible to operate in such a regime, particularly in the case of high viscosity fluids (e.g., polymers), shear-sensitive material (e.g., mammalian cells), and at small length scales (e.g., microfluidics). Mixing in such situations is inherently laminar.…”
