DragForce_SquareBeam_rounded
Procedure DragForce_SquareBeam_Rounded returns the drag force on a square beam of infinite length (with rounded edges) in cross flow
Inputs
Fluid$ - the name of any fluid in the EES data base. Fluid$ may be a string constant or a string variable.
T - temperature in the defined unit system [F,C,R,K]
P - pressure in the defined unit system [Pa,kPa,bar,MPa,psia,atm]
v - free stream fluid velocity in [m/s, ft/min]
W - length of an edge of the beam [m or ft]
r\W - ratio of the radius of curvature to the length of an edge
Outputs
F_d\L - drag force per unit length [N/m or lbf/ft]
C_d - drag coefficient {optional}
Re - Reynolds number {optional}
This procedure calls function DragCoefficient_SquareBeam_Roundedl to obtain the drag coefficient.
Example:
$UnitSystem SI C kPa
Fluid$='Air'
T=25 [C]
P=Po#
v=10 [m/s]
W=0.1 [m]
r\W=0.1
CALL DragForce_squarebeam_rounded(Fluid$,T,P,v,W,r\W:F_d\L,C_d,Re)
{Solution:
C_d=1.651
F_d\L=9.776 [N/m]
Re=64040
