WebThe drag coefficient for a cylinder that you'll mostly find is for subsonic flow where the main component of drag is standard form (pressure) drag. The main contributor to drag for re-entry vehicles is undoubtedly going to be shock wave drag.Webstreamlining is formed. Consequently, with the increasing turbulence intensity directly in front of the cylinder Tu*, the amplitude of the lift coefficient decreases monotonically. Nevertheless, the time-averaged drag coefficient of the streamlined cylinder decreases at Tu*<6.0%, and increases at Tu*>9.0%. The dependence of the average Nusselt

Webthe inertia coefficients for all cylinders approached the potential flow values for both horizontal and vertical forces. The drag coefficients at low KC numbers exhibited large values and these coeffi-cients decreased sharply with increase in KC number for all cylinders. The high drag coefficients at low KC numbers are associated with the flow ...WebFeb 2, 2011 · Figure 2 shows c D vs. Re for a single cylinder. At low Re, drag is due mainly to skin-friction and c D decreases with Re. By Re = 200, drag is almost entirely pressure-related and c D is fairly constant; the slight rise in the range 2 × 10 3 - 2 × 10 5 is a result of wake turbulence and narrowing of the wake due to upstream movement of the ...
