Modeling fluid outflow from a channel consisting of three different segments

The topic of the article is modeling fluid outflow from a channel consisting three different segments. subject research sections. discusses parameters flow in segments converging section, section constant radius and expanding section. Research methods are based on Newton's rheological law; continuity equation Navier-Stokes equation, which basic equations flow; method mathematical analytical solution. Expressions hydrodynamic for each segment, with successively located radius, sections, determined by method. Analytical expressions obtained pressure average rate where there rectilinear inlet area, cylindrical outlet area. solutions make it possible to determine zone vibration baffle pipeline transport such geometry that damps vibrations caused transition sections channels hydraulic drives other flow, set improve flow.
