Abstract
This work consists of determining the mean axial velocities of the liquid and gas in the exit orifice of the effervescent atomizer, dimensionless interface diameter, axial reaction of the effervescent atomizer and Reynolds number of the liquid by applying the control volume method. Ten effervescent atomizers operating under different atomization conditions were selected. The developed method allows obtaining some variables in the exit orifice of the atomizer. From these variables it was determined that the interval for the liquid exit velocity, gas exit velocity, dimensionless interface diameter, axial reaction and Reynolds number of the liquid was [16.053, 66.173 m/s ], [0.492, 10.172 m/s], [0.550, 0.957], [-3.449, -88.502 N] and [126.949, 426.598], respectively. From the results obtained, it was concluded that the estimates of the variables of interest are consistent with the experimental observations, thus validating the method developed for future studies in the effervescent atomization of other liquids.
