Empirical correlations for axial dispersion coefficient and Peclet number in fixed-bed columns

Journal of Chromatography A, 2017
In this work, a new correlation for the axial dispersion coefficient was obtained using experimental data in the literature for axial dispersion in fixed-bed columns packed with particles. The Chung and Wen correlation, the De Ligny correlation are two popular empirical correlations. However, the former lacks the molecular diffusion term and the latter

Measurement of heat-transfer coefficient and axial-dispersion coefficient using temperature oscillations

Experimental Thermal and Fluid Science, 1993
Abstract A periodic transient test technique based on the axial dispersion model is proposed for the determination of both heat transfer coefficients and axial dispersion coefficients in heat exchangers. The model uses a parameter called the axial dispersive Peclet number to account for the deviation of the flow pattern from ideal plug flow. It takes

Axial dispersion coefficient in high-speed counter-current chromatography

Journal of Chromatography A, 2009
Experimental measurements of axial dispersion coefficients in high-speed counter-current chromatography have been carried out in the single-phase and two-phase modes. Axial dispersion coefficients were calculated from the residence time distribution curve (or the elution profile).

On the constancy of axial dispersion coefficients in liquid fluidized beds

The Chemical Engineering Journal, 1992
Abstract The assumption of constant axial dispersion coefficient in residence time distribution (RTD) experiments is examined for liquid fluidized beds. Experimental results show this assumption to be violated in short beds. A quantitative criterion is proposed for the constraint required to achieve the true value of the axial dispersion coefficient ...

Experimental determination of axial dispersion coefficient in a bubble column

Chemical Engineering Science, 1980
Abstract A new graphical method of finding axial dispersion coefficients in a bubble column is developed. This method requires only the area above an experimental curve, thus is simpler than the conventional method of curve fitting. The new method is used to find the dimensionless dispersion number in the bubble column and shows that the dispersion ...

Liquid backmixing in bubble columns and the axial dispersion coefficient

AIChE Journal, 1998
AbstractLiquid backmixing in bubble columns is commonly described using the 1‐D axial dispersion model, wherein all the contributing mechanisms leading to liquid macromixing are lumped into a single axial dispersion coefficient. No relationship has been reported that allows the quantification of various fluid‐dynamic contributions to the axial ...
