Pin-fin plate-fin, surface PF-4(F)

 

 

Procedure Compact_HX_ND('pf_plate-fin_sPF-4F', Re: f,j_H) is a non-dimensional procedure that returns the friction factor and the Colburn j factor for external flow through a pin-fin plate-fin heat exchanger with surface PF-4F given the Reynolds number. The values calculated are based on a best fit curve to experimental data. These data are from Kays and London (1984) p. 260.
