No / This paper presents an integration procedure for the Reynolds-averaged Navier-Stokes equations for the determination of the
distribution of the streamwise velocity using the vertical component. This procedure is dedicated to the outer region and central part of
channels. The proposed model is applicable to both rough and smooth flow regimes, provided the velocity at the inner-outer boundary
has been properly defined. To generate a simplified expansion, a number of hypotheses are proposed, focusing in particular on the analytical
modeling of the vertical component by adopting a negligible viscosity. The proposed hypotheses are validated by the experimental data
existing in the literature. The proposed simplified expansion is studied through a sensitivity analysis and proved consistent in regards
to model experimental data. The proposed model seems capable of demonstrating different kinds of flows, including dip phenomenon flow
patterns.
