Аннотация

The statistical theory of turbulent flows under intermittency conditions is revised, and a new method is developed for statistical description of such flows. It is shown that the model as constructed here is more accurate than those previously proposed for intermittent flows. Some results are presented of conditioned and unconditioned averaged characteristics of several turbulent shear flows as predicted by the model. These predictions are applied via comparison with experimental date
