Forced convective heat transfer from a single row of cylinders placed in the longitudinal and the transverse direction to the flow was investigated experimentally. The average Nusselt numbers from the longitudinal row of six-cylinders were first measured in the range of Reynolds numbers Red =160-2000 and the spacing between cylinders G =5-70mm, where the cylinder diameter d were varied as d=8.4 and 14.4mm. Similar measurements were also carried out for the transverse row of multiple cylinders. It is found that the average Nusselt numbers NuG are well correlated with the non-dimensional parameter ReG (G/d) for both cases of the longitudinal and transverse row of cylinders, where NuG and ReG stand for the Nusselt and Reynolds numbers based on the cylinder spacing.
