Existence of hypercyclic operatorsout turbulence model. The critical flows and the pressure distribution on the cylinder surface are numerically investigated in detail. Their structures and unsteady characteristics are discussed in case the drag crisis of the cylinder occurs.

However, some measurements on two-dimensional flow past two tandem cylinders and flow past a single finite length cylinder were also carried out for the purposes of calibrating the test rig and later the comparison of results.

Unsteady Base Pressure Measurements in the Near Wake of a Cylinder With Imposed Three-Dimensional Distantaneous base pressure of a circular cylinder were investigated. Measurements indicate a direct coupling to the shedding frequency between the stagnation-line and base-pressure signals. A low frequency component in the base pressure power spectra was found and was directly related to the irregular shedding observed in the wake.

Flip-Flopping Flow Around Two Bluff Bodies in Tandem Arrangement The average time interval for two patterns was much larger than both the vortex-shedding period and the time scale of the free-stream turbulence, being strongly dependent on the turbulence intensity.

Development of the Near Wake Structure on a Cantilevered Circular Cylinder with a Free-Endre proposed. Thus, for the case taken as reference, namely Al=5, three different zones are differenciated along the span of the cylinder and their modifications with the variation of the aspect ratio are established as well as that of the vortex shedding process.
