In this study, the heat transfer, which is placed straight into the flow and over the heated cylinder, was numerically studied within a straight-cutting channel. The ANSYS-FLUENT 14 package program has been used using the Final Volume Method (SHM) to solve the flow-managing Navier-Stokes equations. In the study, three different turbulence models (Std. k-ε, RNG k-ε and Realizable k-ε) have been calculated for four different input Reynolds numbers (Re= 4000, 8000, 16000 and 32000). As a result, St. and the numerical results obtained by the RNG k-ε turbulence models have been found to be well compatible with the experimental values. The number of Reynolds, as expected, has also increased the number of Nusselt at almost all points on the cylinder.
