摘要
Results of simultaneous liquid velocity and film thickness fields measurements in the three dimensional waves are presented. The three dimensional waves formed as a result of decay of the forced two dimensional waves were studied. Liquid velocity fields were reconstructed at different distance from the film surface with reference to the specific area of the wave. It was shown that flow in the three dimensional wave has complicated structure with existence of areas with backflow and transverse flows of opposite directions. Main areas of transverse flows existence are lying under main humps of three dimensional waves.
