Библиографическое описание: Approximate solution of the problem of flow in a Far plane momentumless turbulent wake : научное издание / A. V. Shmidt. - Текст : непосредственный // Journal of Applied Mechanics and Technical Physics. - 2023. - Т. 64, № 6. - P. 987-992. - ISSN 0021-8944. - ISSN 1573-8620, DOI 10.1134/s002189442306007x.
Аннотация: The flow in a far plane momentumless turbulent wake is described using a mathematical model obtained from the algebraic Rodi model of Reynolds stresses. The model is similar to the two-parameter (<span class="mathjax-tex">\(k{-}\varepsilon\)</span>) turbulence model in the far-wake approximation with a modified empirical constant in the diffusion terms of the equations. A group-theoretical analysis of the mathematical model of the wake is carried out, and a self-similar reduction of the model equations to a system of ordinary differential equations is performed. An approximate solution of the corresponding boundary-value problem is constructed using an asymptotic expansion of the solution in the vicinity of a singular point.
