Effect of cyclist’s posture and vicinity of another cyclist on aerodynamic drag

Autor: S.J. Chishohn, M. M. Zdravkovich, N. Hicks, M. W. Ashcroft

Publikováno v: The Engineering of Sport ISBN: 9781003078098

Two long-established and well-known methods of drag reduction are the posture of the rider and aerodynamic interference when two riders are in close vicinity. The aim of the tests on the model and full-scale cyclists is to quantify the drag reduction

Some aerodynamic aspects of coin-like cylinders

Autor: A. J. Flaherty, I. A. Skelhorne, M. G. Pahle, M. M. Zdravkovich

Publikováno v: Journal of Fluid Mechanics. 360:73-84

The aspect ratio of short coin-like cylinders is defined as L/D, where L is the length and D is the diameter of the cylinder. Force and pressure measurements are extended down to L/D=0.025. The force measurements indicate an unexpected increase in dr

Inadequacy of a Conventional Keulegan-Carpenter Number for Wave and Current Combination

Autor: M. M. Zdravkovich

Publikováno v: Journal of Offshore Mechanics and Arctic Engineering. 118:309-311

The physical consideration, taken as a starting point, has been based on the change of duration of each wave half-cycle by the superposition of a current. The Keulegan-Carpenter number could reflect that feature if the wave plus current velocity repl

A Reflection on Two Modes of Eddy Shedding at Re = 180 ~ 300

Autor: M. M. Zdravkovich

Publikováno v: Bluff-Body Wakes, Dynamics and Instabilities ISBN: 9783662004166

The word ‘reflection’ means to review something casually and often inconclusively, according to the Webster Dictionary. This has been attempted in this paper where the two modes of eddy shedding are briefly reviewed. It is argued that in the tran

Suppression of Vortex Shedding from Satellite Risers in a Current

Autor: J. L. Baldaro, M. M. Zdravkovich

Publikováno v: Advances in Underwater Technology, Ocean Science and Offshore Engineering ISBN: 9789048142507

Wave and current-induced oscillations have plagued marine risers. An enormous experimental research and computational effort are expended in measuring and predicting the response of risers due to the vortex shedding excitation. Another promising aven

Flow Visualization of Separation Bubble on a Circular Cylinder

Autor: Y. Tomonari, M. M. Zdravkovich

Publikováno v: Flow Visualization VI ISBN: 9783642848261

A blockage tolerant test section based on a modified Parkinson’s design allows tests up to Re = 4.3 × 105. A schlieren method is used to visualise boundary and free shear layers emanating from a slightly heated circular cylinder. Colour photograph
