The Effect of Aspect Ratio on the Drag of Bare Cylinders

WebThe drag coefficientis a number which aerodynamicists use to model all of the complex dependencies of dragon shape inclination,and some flow conditions. The drag coefficient (Cd) is equal to the drag (D) divided by the quantity: density (r) times reference area (A) times one half of the velocity (V) squared. This slide shows WebThe large dive in the drag coefficient is called the drag crisis. This happens when the boundary layer over the cylinder transitions from laminar to turbulent. Turbulent boundary layers are more resistant to separation, so the flow stays attached longer resulting in decreased form drag. WebThere is no separation. The drag is all due to skin friction. As the Reynolds number is increased this drag decreases. At Reynolds numbers around 2 - 30, there is a separation of boundary layer, but the wake is of a limited … christmas games for women\u0027s luncheon
