The droplet concentration distribution in an atomizing scrubber was calculated based on droplet eddy diffusion by a three-dimensional dispersion model. This model is also capable of predicting the liquid flowing on the wall. The theoretical distribution of droplet concentration agrees well with experimental data given by Viswanathan et al.1 for droplet concentration distribution in a venturi-type scrubber. The results obtained by the model show a non-uniform distribution of drops over the cross section of the scrubber, as noted by the experimental data. While the maximum of droplet concentration distribution may depend on many operating parameters of the scrubber, the results of this study show that the highest uniformity of drop distribution will be reached when penetration length is approximately equal to one-fourth of the depth of the scrubber. The results of this study can be applied to evaluate the removal efficiency of a venturi scrubber.

“…4. For a same jet penetration (according to Viswanathan et al (1983) definition, see Eq. (1)), a higher number of injection orifices mean that there is more liquid in the throat of the Venturi.…”

“…Injection occurred through one to six 0.001 m orifices located at the beginning of the throat. By varying the gas and liquid flow-rates, it was possible to achieve dimensionless jet penetrations (as defined by Viswanathan et al (1983) from 0.05 to 0.85. Gas velocity in the throat was 50, 70 and 90 m/s.…”

“…Film fraction is defined as the fraction of the total injected liquid which flow as film attached to the equipment walls. The maximum jet centerline penetration (l max ) was defined by Viswanathan et al (1983) as the transversal distance travelled by the jet until it becomes parallel to the gas main flux. This distance can be made dimensionless if divided by the distance between the wall which contains the jet injection orifice and its opposing wall.…”

“…This distance can be made dimensionless if divided by the distance between the wall which contains the jet injection orifice and its opposing wall. Viswanathan et al (1983) (1) Gonçalves et al (2004) and Daher (2008) have shown that the jet penetration defined by Eq. (1) is one of the most important parameters affecting film fraction in Venturi scrubbers.…”
