This work proposes an original approach for modeling the entrainment of droplets in a horizontal
stratified two-phase wavy flows. This mechanistic model is based on the ripple-waves
breakout and entrainment phenomenon by estimating the liquid mass pulled off the wave crests
during their fragmentation. The paper presents the modeling procedure for estimating the wavelength
of these ripples and the related entrained liquid volume. In regards to these parameters,
it is shown that a relatively simple methodology can be obtained to ease the implementation in
a system code. This work aims at substituting the current existing empirical correlations in the
system code CATHARE 3 by using a flowfield for a liquid dispersed phase.
