"To pass a car, you need to know precisely where the minimum drag is for you and the maximum drag is for him.
While the drag force of a porous particle having a low to moderate permeability is a monotonic, decreasing function of the separation distance, a weak maximum drag may occur for a sphere with a very high permeability at a certain distance from the wall.
The maximum drag reduction was obtained for polymer concentrations higher than 20 ppm in the test section.
The number of blades used for the airborne wind turbine must be determined to obtain a maximum drag force [25].
The first two modifications resulted in a maximum drag reduction by the W trawl of up to 11% for a 1.14 × increase in spread.
The maximum drag coefficient shift to the left at smaller angles and the drag coefficient profiles shift also to the left part.
Increasing polymer concentration resulted in further reduction in friction factors (data points get close to the maximum drag reduction asymptote), and consequently, drag reduction efficiency increased.
The maximum drag-reduction was 83% at 25 °C for 200 ppm surfactant solution.
We recommend eye drops for maximum drama.
The optimization is carried out for maximum lift and minimum drag.
Indeed, at 75mph the 911 Turbo's front fascia wing extends down slightly and rear wing lifts for maximum control with minimal drag.
