FC_horizontal_cylinder_ND
The procedure FC_horizontal_cylinder_ND(Ra, Pr: Nusselt) returns the Nusselt number for a horizontal cylinder immersed in a fluid given the Rayleigh and Prandtl numbers. The Rayleigh number should be calculated based on the diameter, D.
Inputs:
Ra - Rayleigh number based on cylinder diameter, D [-]
Pr - Prandtl number of fluid [-]
Outputs:
Nusselt - Nusselt number [-]
Notes:
The procedure FC_horizontal_cylinder_ND is called by the dimensional variant FC_horizontal_cylinder to determine the Nusselt number. The procedure uses the correlation provided by Churchill and Chu (1975). This correlation is valid for all Pr and 1e-10<Ra<1e12.
Example:
Ra=1.5e6
Pr=2.0
Call fc_horizontal_cylinder_nd(Ra, Pr: Nusselt)
{Solution:
Nusselt=18.32}
