The Study of the Structure of Laminar Currents in Recirculating Channels with Developed Surface

In order to research influence of parameters of the developed surface on structure of a laminar current of viscous incompressible liquid in ring channels the computing model, and algorithm of creation of profiles of speed has been offered. This case deals with a homogeneous layer of obstacles – cylindrical protrusions, distance between which ensures the absence of hydrodynamics interactions. Numerical calculations allowed analyzing dependence of the maximum and average speeds of a stream from density of ledges on a surface of the channel and from their height.
