During the collision of two planar streams, atomization characteristics of liquid sheets are closely
related to the surface wave. The present study focuses mainly on the features of the surface wave in planar liquid streams colliding. For the impingement of low-speed laminar jets, the formation and development of the surface wave stem from the interaction between the sheet and surrounding air.
A linear stability-based model considering the cross-sectional velocity profile is used to determine
the features of the surface wave. To derive the velocity distribution in proximity to the impact point
and determine the characteristic cross section, a two-dimensional model of planar liquid streams colliding is established, and results show that the central velocity of υx is the lowest and the overall velocity gradually tends to smooth when the cross section moves away from the impact point. The effects of Weber number, gas-liquid density ratio, velocity profile, and impingement angle on the
surface wave features are also explored.
