The free shear layer is suitable for understanding the basic mechanism of randomization. Sound from a loud-speaker was used for introducing ordered velocity fluctuation in the layer. Three kinds of shear layer were tested and compared. A quantitative expression of the degree of randomness was accomplished by the elementary-wave analysis. The concept of neighbor randomness was introduced for another way of describing randomization. The randomization process of three shear layers does not show any significant difference.
The detailed structure of randomization process of free shear layers
