Application of results of analysis of transient vortex flows of ideal fluids to description of the turbulent mixing layer
Abstract
The paper examines the mechanism of capture and setting into rotational motion of two initially translationally flowing fluid masses. Two transient vortex flows of an ideal fluid are used as an illustration. It is shown that the rate of growth of a vortex cluster, determined from a numerical experiment, can be used to compare the model description of flow in a turbulent mixing layer with the experimentally observed spreading rate (spreading angle) of the turbulent mixing layer at the interface between two streams moving at different velocities.
