Louvered plate-fin, surface 3/4-11.1
Procedure Compact_HX_ND('l_plate-fin_s34-111', Re: f,j_H) is a non-dimensional procedure that returns the friction factor and the Colburn j factor for external flow through louvered plate-fins with surface 3/4-11.1 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. 240.
