Abstract

The results of numerical simulation of internal flows of liquid fuel in the tanks with baffles of the spacecraft moving in the Earth's orbit. The flow structure in the vicinity of walls - the parietal region, wakes around the edges of walls, etc. An evaluation of the structure and nature of the circulating currents in the range of Reynolds numbers 700-12500, allowing to build a picture of an axially symmetric hydrodynamic circulation flow. Analysis of the numerical simulation results allows to set specific field of inertial flows, the structure of circulation in the meridional plane and especially their impact on the main stream velocity, which determines the value of a force on the vessel walls and interior partitions.
