Computational simulation of the flow formation in the circular pipe after the honeycomb

In this paper the mathematical modeling of water flow in channel behind rectifying device (honeycomb) is carried out. Influence of honeycomb on velocity field in channel and change of velocity profiles of liquid in channel sections along its length is considered. The analysis of influence of value of flow rate in the channel on velocity profiles on channel height is carried out. The distance from honeycomb where there is justification of fluid velocity profile due to internal friction of layers of liquid is defined.
