Based on modified two-equation model of turbulence the numerical model of dynamics of cylindrical localized zone of turbulent mixing in a longitudinal uniform shear flow of homogeneous fluid has been constructed. The results of numerical experiments demonstrate a significant turbulent energy generation caused by the effect of shear flow. The question of similarity of the flow with respect to the shear Froude number has been under consideration. The results of numerical experiments show the similarity of flow for large values of this parameter which correspond to small values of velocity gradients of shear flow.
Keywords: mathematical model of turbulent patch in a shear flow, Rodi’s algebraic Reynolds stresses model of turbulence, numerical modeling.
