Paper Abstract

For a more comprehensive understanding of atmosphere and oceanic circulations that generally affect climatic conditions in many regions and, in particular, influence their ecology problems, it is useful to investigate the flow pattern in rotating cylindrical vessels. In this research two interesting 3D gasdynamical phenomena were discovered by flow visualization in the meridional plane of a rotating cylindrical channel. The first phenomenon is nonstationary process after abrupt termination of a channel's rotation with the development, on its internal side surface, of periodically spaced local nonuniformities that have different growth rate in the axial and radial directions. The second phenomenon is establishment of an uncommon extensive intermittent flow pattern after the rotating channel, initially open on the one end, is closed with a stationary plate with a small gap between it and the end-wall of the rotating channel for ambient air inflow into the channel.
