Book excerpt: A brief experimental investigation was made to determine the effect of inclination on the Strouhal Number of circular cylinders at Reynold's numbers from 4,000 to 65,000. It was found that the Strouhal Number based on the normal velocity component remained constant to a good approximation. Spectral techniques showed that the energy of the shed vortices dispersed in frequency and decreased in significance with increasing inclination, such that for angles less than 40 degrees the shedding energy was negligible compared to the general wake turbulence energy, at 7.5 diameters downstream from the cylinder. Other wake properties were briefly investigated. These included the decay of the u-component of turbulence downstream and the behaviour of the wake spectra with inclination, speed and wake location.

This book was released on 1986 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation has been carried out on the flow transitions around a smooth circular cylinder in the initial stage of the critical Reynolds number region, where drag coefficient starts to decrease. In this Reynolds number region, intermitent reattachment of the separated boundary layer was found, while only initial separation position excursion was observed in the subcritical region. Large spanwise variations in the surface pressure and wake velocity observed in the first critical subregion were associated with local wake width pulsations caused by spanwise phase variations in the unsteady flow reattachment.

Available in PDF, EPUB and Kindle. Book excerpt: The recently reported phenomenon of asymmetric flow separation form a circular cylinder in the critical Reynolds number regime has been confirmed in a water-tunnel experiment. For the first time, an attempt was made to visualize the wake of the cylinder during the transition from subcritical to critical flow and to correlate the visualizations with lift and drag measurements. The occurrence of the dominant asymmetric-flow state was quite repeatable, both when increasing and decreasing the Reynolds number, resulting in a mean lift coefficient of C sub l approx = to 1.2 and a shift in the angle of the wake by about 12 deg. A distinctive step change in the drag and shedding frequency was also found to occur. A hysteresis was confirmed to exist in this region as the Reynolds number was cycled over the transition range. Both boundaries of the asymmetry appear to be supercritical bifurcations in the flow. The asymmetry was normally steady in the mean; however, there were instances when the direction of the asymmetry reversed and remained so for the duration of the Reynolds number sweep through this transition region. A second asymmetry was observed at a higher Reynolds number; however the mean lift coefficient was much lower, and the direction of the asymmetry was not observed to reverse. Introducing a small local disturbance into the boundary layer was found to prevent the critical asymmetry from developing along the entire span of the cylinder. (Author).
