Abstract

A two-dimensional case of the process of laminar flow passing through
a pipe constriction is investigated. The two-dimensional statement corresponds
to the case with a three-dimensional flow between two parallel planes. A cellular
automaton model of a flow is used, which has an integer alphabet of cell states and
a synchronous operation mode. The dependences of the velocity and pressure on
the coordinate along the direction of a flow for different constriction clearances and
different pressure gradients at the ends of the pipe are obtained.
