On the nonlinear dynamical system of amplitude equations corresponding to intersections of bifurcations in the flow between permeable cylinders with radial and axial flows
Аннотация:
In the present work, we study various modes that arise after a
circular Couette flow loses its stability in the presence of an
axial flow due to a constant axial pressure gradient and a
radial flow through the permeable walls of the cylinders. The
basic object of our investigation is a nonlinear system of
amplitude equations describing multiple flow bifurcations
between permeable cylinders. Different bifurcations will be
investigated theoretically with application of numerical
methods.
