Permeability Coefficient
 

In order to finalize my last test at university of florence as mechanical engineer, i'd like help for the following scope: simulation of a vacuum steam condenser consisting of A-roof finned boundle by using Star-CD. My question is how to simulate a finned tube bank airside pressure drop as calculated by Robinson and Briggs formula. In particular my interest is in finding, in the right way, alpha and beta coefficient for Star-CD.

yours friendly, Michele
