Transition and turbulence in fluid flows and low-dimensional chaos.

Research output: Book/ReportBook


Measurements made in the wake of a circular cylinder chiefly in the Reynolds number range of about 30-10 SUP 4, were analysed to show aspects of similarity with low dimensional chaotic dynamic systems. It is shown that initial stages of transition to turbulence are characterized by narrow windows of chaos interspersed between regions of order. Several alternations between order and chaos below a Reynolds number of about 200 were observed and it is suspected that many more exist even in the higher Reynolds number region. Each window of chaos is associated with a near discontinuity in the vortex shedding frequency and the rotation number, as well as a dip in the amplitude of the vortex shedding mode. (from paper)
