Drag Coefficient The drag coefficient quantifies the drag or resistance of an object in a fluid environment. Any object moving through a fluid experiences drag - the net force in the direction of flow due to pressure and shear stress forces on the surface of the object. The drag force can...

For slender columns, the influence of the drag force on the platform can be calculated by the Morison equation, and the drag force per unit length of column is (A-26)fD=12ρCDD(wx−x˙)|(wx−x˙)| where: D is the diameter of column; CD is the coefficient of drag force; wx ...

When taking into account other factors, this relationship becomes FD=12CρAv2FD=12CρAv2, where C is the drag coefficient, A is the area of the object facing the fluid, and ρ is the density of the fluid. (Recall that density is mass per unit volume.) This equation can also be ...
One of the possible reasons behind the observed differences in the drag coefficient per unit size for different particles might be the change in their effective size. For PAAm-grafted particle, the inside of the particle is a hard sphere, and the grafting of polymer can increase the effective ...
jack-uptrusslegdragcoefficientroughnessThe accurate prediction of drag coefficients for truss-type jack-up legs is an important part of a unit's design. Over the past 14 years, a series of windtunnel tests have been conducted on both square and triangular cross-section leg configurations. A ...
