DragCoef_Ellipticalbeam
Function DragCoef_Ellipticalbeam(Re) the drag coefficient for an elliptical beam of infinite length in crossflow
Inputs
Re - Reynold's number (Use D1 (the dimension parallel to the flow) to determine Re)
D2\D1 - ratio of the dimension perpendicular to the flow to that parallel to the flow (Valid values are between 0.125 and 2)
Outputs
DragCoef_Ellipticalbeam - drag coefficient [-]
