functionSherwoodNumberMuzychka
calculates sherwood number out of reynolds and prandtl number according to Muzychka et. al
Information
This function calculates the Sherwood number for a rectangular duct according to Muzychka and Yovanovich [1].
The dimensionless length zStern as input has to be calculated as
follows.
zStern = (sduct ⁄ √Across-section ) ⁄ (Re Pr )
