摘要：

An LIF line scan system is presented and used to obtain unobtrusive mean and angle resolved concentration measurements in a continuously operated stirred tank agitated with a single Rushton turbine. The measurements showed that the trailing vortex structures caused regions of elevated concentrations gradients and concentration fluctuations between blade passages. In addition, on the centre line of the tank, whilst macromixing was always complete, micromixing was less complete than in other regions of the tank. Compared to point measurement techniques, the line scan system made data collection more comprehensive and convenient and the determination of a line of data allows the possibility of the correction of beam attenuation and the extension of the technique to a larger scale. © Springer-Verlag 1998.
