Abstract
When creating cellular structures, one of the tasks is to study the flows of liquids in the cavities of structures in order to obtain data on the velocities, pressures, and features of the current lines. The properties of cellular structures depend on the geometry of the cavities and their relative position.
The article describes the sequence of stages of modeling fluid flow in the cavities of cellular structures and the results of variant calculations for various types of such structures.
