Cylinder frontal area
WebThe drag caused by the cylinder can be calculated through two different methods: control surface analysis consisting of pressure measurements around the cylinder, and control volume analysis consisting of velocity measurements taken before and after the cylinder. WebDec 22, 2024 · However, the C D it largely independent of the frontal area, although it is calculated from it. C D = 2 ⋅ D r a g ρ u 2 A where: D r a g aerodynamic force ρ air density u is velocity A is frontal area. So for example, changing the angles on a rear spoiler, has zero to little effect on the frontal area, but it can change significantly the C D.
