Heat transfer analysis of double tube heat exchanger with wavy inner tube

The effect of the design on heat transfer is numerically investigated by using wavy inner tube in a double-pipe exchanger. A was used to give turbulent fluid along double In numerical study, ANSYS 12.0 Fluent code program used, and basic protection equations were solved for steady-state, 3-D flow conditions. study examined at Reynolds numbers ranging from 2700-5300. obtained results compared with experimental data performed under same As result this comparison, after it seen that analysis compatible each other, wave number increased analyzed fluent program. When as analyzes evaluated, highest 16 exchanger, which has waves counter increase 270% straight tube.
