Abstract
In this paper, the numerical analysis of the flow with heat transfer in two-dimensional pipe attached fins was studied. The analysis was carried out for the several of combination models in the length and the number of fin over a wide range of Reynolds number. The k-ε turbulence model was chosen to calculate the velocity and temperature. The results obtained were as follows; the temperature differences between the inlet and outlet decreased and presented distinction each other with increasing Reynolds number, the pressure drag coefficient was constant approximately in each pipe, and temperature difference and pressure drag coefficients were especially influenced by long fin.
