Approximate Method for Calculating the Velocity Profile of a Two-Dimensional Stationary Turbulent Liquid Flow

Journal of Engineering Physics and Thermophysics Aims and scope

A developed stationary two-dimensional turbulent flow of an incompressible fluid in channels and pipes is studied. The entire flow was divided into three zones: a laminar zone near the boundaries of the channel (pipe) and a transition and turbulent ones that follow. The laminar zone and part of the transition zone were combined into one zone, for which a linear flow velocity profile was assumed in the channel and a parabolic velocity profile with corresponding additional functions in the pipe. For the zone consisting of a turbulent core and the rest of the transition zone, a logarithmic flow velocity profile was taken. Comparison of the results of calculations with experimental data has been carried out, which has shown their acceptable agreement.
