Abstract : Results of laboratory experiments dealing with wave formation and droplet entrainment in two-phase flow systems are presented here. Data concerning the effective interfacial shear stress between the gas and liquid are given and compared with similar air-sea data. By means of an extrapolation technique, the critical velocity for droplet entrainment in laboratory experiments is related to the corresponding critical velocity in the air-sea case. Analysis of a simplified model of the entrainment process indicates a reduction in the effective interfacial shear stress with increasing entrainment. However, the stress reduction is less than in direct proportion to the amount of entrainment. (Author)
