Study the Axail Dispersion Model in Ion Exchange Column

open access: yesAl-Khawarizmi Engineering Journal, 2009
A mathematical model is developed which predicates the performance of cylindrical ion exchange bed involving comparing of axial dispersion model for cation exchange column with different assumption, this model permits the performance to predicate the ...

Axial dispersion of the liquid phase in vertical tubular contactors with static mixers

open access: yes, 1986
Axial dispersion characteristics in the liquid phase have been determined for three selected types of static mixers using the impulse response technique in a vertical tubular contactor for single phase (water) and two phase (water-air, cocurrent flow ...

Liquid-Phase Back mixing in Bubble Columns

open access: yesTikrit Journal of Engineering Sciences, 2013
Liquid-phase axial dispersion coefficients have been measured for air-water system in bubble columns of 10, 15 and 30 cm diameter. The experiments are carried out using a transient method (the tracer response method).
