METHOD OF DIFFERENTIAL CONSTRAINTS: LOCAL EQUILIBRIUM APPROXIMATION IN A PLANAR MOMENTUMLESS TURBULENT WAKE
Autor: A. G. Demenkov, G. G. Chernykh, Vladimir N. Grebenev
Publikováno v: Journal of Applied Mechanics and Technical Physics. 62:383-390
It is revealed that the local equilibrium approximation (algebraic parametrization of triple correlations of turbulent fluctuations of a vertical velocity component) in the problem of a planar momentumless turbulent wake is a differential constraint

On Mathematical Modeling of Swirling Turbulent Wakes with Varied Total Excess Momentum and Angular Momentum
Autor: G. G. Chernykh, Alexey V. Schmidt, O. V. Kaptsov, A. G. Demenkov
Publikováno v: Journal of Engineering Thermophysics. 29:222-233
The flow in swirling turbulent wakes with varying total excess momentum and angular momentum is described using two second-order mathematical models. The first one includes averaged equations of momenta, turbulence energy balance, and dissipation rat

Mathematical Modeling of Evolution of Swirling Turbulent Jet in Coflowing Stream
Autor: G. G. Chernykh, A. G. Demenkov
Publikováno v: Journal of Engineering Thermophysics. 28:400-409
A numerical modeling of a swirling turbulent jet in a coflowing stream was carried out. The flow description involved two second-order mathematical models. The first one includes the averaged equations of motion and the differential equations for tra

Dynamics of a Swirling Turbulent Wake past a Sphere
Autor: G. G. Chernykh, A. G. Demenkov
Publikováno v: Journal of Engineering Thermophysics. 27:319-326
Using a mathematical model, which includes the averaged motion equations, differential transport equations of normal Reynolds stresses and dissipation rate, we carried out numerical modeling of evolution of a swirling turbulent wake with nonzero tota

Numerical models of a far turbulent wake of an elongated body of revolution
Autor: O. A. Druzhinin, A. G. Demenkov, G. G. Chernykh
Publikováno v: Thermophysics and Aeromechanics. 23:929-932
The work presents a comparison of numerical models of a far turbulent wake of a towed elongated body of revolution in a homogeneous fluid: model based on the direct numerical simulation, and two semi-empirical models involving the equation of the tur
