Aerodynamic characteristics of a circular cylinder either stationary or rotationally oscillating around its axis in uniform viscous flow are studied by numerical calculation and by experiment. The method and results of numerical solution of the Navier-Stokes equations by the finite difference analogue are presented as well as measurements for the lift and the drag forces acting on the cylinder made by towing test models in still fluid in a range of Reynolds number, Re=40 to 6100. Good agreement is obtained between the calculated results and the experimental ones at Reynolds numbers Re=40 and 80,concerning the steady and unsteady aerodynamic parameters, the phenomenon of the so-called synchronization and so on. It becomes clear from numerical calculation that there may be a close relationship between the time-variation of the flow pattern and that of the lift force on an oscillating cylinder. Also by experiment the influence of Reynolds number on the aerodynamic parametersand the phenomenon of synchronization are examined. |
