摘要: Abstract In this paper, the heat transfer and flow characteristic of air over flat finned tube with perforated non-perforated fin have been carried out numerically. The mesh generation finite volume analyses conducted using Ansys 15 a RNG k–e turbulent model to estimate coefficient pressure drop. free stream velocity ranging between 3,4,5,6, 7 m/s applied for all cases in simulation verified available data. A satisfactory agreement was found percent results references maximum deviation 7% circular solid fin. present considerable enhancement Nusselt number perforation technique, where provide 8.5%, 13.6% 18.4% circular, square triangular respectively. Triangular offers finding due increment comparing
