Impinging_Jets_ARNHex_ND



Procedure Impinging_Jets_ARNSquare_ND(Re, Pr, L\D, H\D : Nusselt) calculates the average Nusselt number for a hexagonal array of round nozzles each  with slot diameter D positioned perpendicular to a plate with its exit a distance H from the plate. 

Inputs
Re - Reynolds number with characteric length equal to the diameter of the nozzle.
Pr - Prandtl number
L\D -  the ratio of the distance between nozzle centers and the nozzle diameter
H\D- the ratio of distance of the nozzle to the plate to the nozzle diameter

Outputs
Nusselt - average Nusselt number [-]

Notes:
The correlation used in this procedure is applicable for the following conditions:
     2 < H\D < 12
     4.4 < L\D > 14
    2000 < Re < 100000

Example:
Re=10000
Pr=0.7
H\D=4
A_r=pi/4*D\L^2
A_r=0.01
L\D=1/D\L
Call impinging_jet_arnhex_nd(Re, Pr, L\D, H\D : Nusselt)

{Solution
Nusselt=34.04 [-]
}
