DragCoef_RectangularBeam

 

 

Function DragCoef_RectangularBeam(Re)  the drag coefficient for a rectangular beam of infinite length in crossflow given Reynold's number.

 

Inputs

Re - Reynolds number

W\H - ratio of dimension in the flow direction to the dimension perpendicular to the flow

 

Outputs

DragCoef_RectangularBeam - drag coefficient [-]
