| The new mathematical model for a stream function of the meandering jet is suggested. It based upon a modification of the von Karman vortex street stream function [1], The processes of mixing and transport across the jet by interaction with rings [2] as well as by initiation of the pinched off eddies are considered. To study mixing across the jet we examine deformation of circular area back in time, so we can determine from which part of the jet this area is composed. Numerical simulations show that approximately half of the circular area above the third trough of meandering jet may contain warm fluid from a central area of the jet. In this study firstly ways by which warm water from jet transfered into surrounding cold water are shown. |
