... of the present study is to assess the performance of droplet entrainment correlations in which droplets are created by shear at the disturbance waves' crests. A model framework based on the 1-D Two-Fluid model is employed with a high-resolution mesh. The model allows capturing the automatic evolution of the gas...

Second, a new methodology is proposed as an alternative for the droplet concentration profiles prediction assuming an exponential droplet distribution in the vertical diameter. The methodology is built by obtaining empirical correlations using genetic algorithms. The algorithm...
