ON THE COMPLEX REGIMES OF THE TAYLOR-DEAN FLOW BETWEEN TWO ROTATING POROUS CYLINDERS

The appearance of complex regimes in the Taylor-Dean flow between rotating porous cylinders heated up to different temperatures with radial throughflow is studied.As it has already been shown in [13] this flow takes place at the points of intersection of neutral curves corresponding to the axisymmetric and nonaxisymmetric disturbances as vortices and oscillatory modes in the form of traveling waves. The aim of the present paper is to investigate different regimes arising in a small neighborhood of the points of intersection of neutral curves corresponding to the flow instability and bifurcations.
