| Abstract: | Experimental study of forced convection heat transfer in a horizontal circular tube with flag-type insert is performed to investigate the characteristics of fluid flow and heat transfer as well as the influence of the sweep angle of flag-type insert. The working fluid is 30# turbine oil. In experiment, when sweep angle increases the heat transfer coefficient increases at the beginning and shows the highest value at =76,then drops down. However,flow resistance force increases all the time. |

| Keywords: | forced convection heat transfer enhancement sweep angle of flag-type |
