Minimization Principle for Analytical Solution of Turbulent Flow in Channel

Abstract: The analytical solution for turbulent flow in channel presented in Fedoseyev (2023), described the mean turbulent flow velocity as a superposition of the laminar (parabolic) and turbulent (superexponential) solutions. In this study, the coefficients of superposition are proposed to obtain through the minimization principle, the principle of minimum viscous dissipation. The obtained analytical solutions agree well with the experimental data for turbulent flow.
