The effects of free stream turbulence integral length scale and turbulence intensity (root-mean-square stream-wise component of velocity fluctuation) on the rate of forced convective heat transfer from a heated horizontal circular cylinder in a cross flow of air were investigated experimentally. An internally heated 5.1 cm (2&inches;) diameter aluminium cylinder was placed horizontally in an 86 cm wide by 66 cm high (34&inches; by 26&inches;) wind tunnel. The power supplied by the internally embedded heater was kept constant in order to maintain uniform surface temperature. A perforated plate was placed at the entrance to the test section to generate the free stream turbulence. To eliminate the effect of the mean free stream velocity, the Reynolds number based on the cylinder diameter was kept at 27,700 +/- 1850. By altering the solidity area ratio, the diameter of the perforated holes and/or the distance downstream of the plate the turbulence integral length scale ratio, L/D, where D is the diameter of the cylinder and the turbulence intensity, Tu, were varied independently.
