Forced Convection Correlations: tube_bank_c1m
Nusselt number correlation constants for forced convection heat transfer. Covers external cross-flow over cylinders (Hilpert circular, noncircular shapes, Zukauskas), tube bank arrays (C1/m constants and C2 row correction factors), and fully developed laminar internal flow in noncircular ducts. Each record provides C and m coefficients for power-law Nu correlations, valid Reynolds number range, and source reference. 51 records from Incropera Chapter 7 (Tables 7.2-7.6) and Chapter 8 (Table 8.1).
