Flow behavior and heat transfer around a circular cylinder at high blockage ratios
Abstract
The effect of a high blockage ratio (between 0.4 and 0.8) on the local mass (heat) transfer from a circular cylinder in the Re range 10,000-100,000 is described. In particular, the local characteristics of mass transfer and the wake flow behavior are measured at typical blockage ratios near the 'critical blockage ratio' where Karman vortices cease to be shed. The correlation between both characteristics are clarified, and additional experiments are conducted to determine the effect of free-stream turbulence on the 'critical blockage ratio'.
