In this study; The heat transfer parameters (Reynolds number, helix angle and pitch) of the axial vortex generators fixed to the pipe inlet were numerically optimized. For this, the Response Surface Method was used. Central Composite Design Face Centered (CCDFC) design was used in the method. 20 analyzes in which 3 different parameters were examined at 3 levels were made with the Fluent program. The heat transfer coefficient (h) was determined as the target function. As a result of the analysis, the square effects of Reynolds number and the combined effect of Reynolds number and angle were found to be statistically significant. Optimum results were obtained for the Reynolds number of 15000, for the angle of 15 ° and for the pitch of 2 mm. A mathematical model is proposed for the heat transfer coefficient determined as the response function.
