Abstract

A correlation method has developed to obtain the instantaneous velocity fields in wave breakers and its spatial derivatives by utilizing the entrained air as tracer. The errors of the method are evaluated and reduced by data processing. The method has applied to the spilling and plunging breakers of the solitary waves. The 3 dimensional behaviors of the flow and vortex are analyzed and discussed through the distributions of the velocity, vorticity, strain rate and two-dimensional divergence of velocity taken from the side and the bottom of the breakers.
