| 摘 要： | Experimental study of forced convection heat transfer in a horizontal circulartube with ladder-shaped flag-type insert is performed to investigate the characteristics of fluid flow ,heat transfer and the influence of width of flag insert.The working fluid is 30# turbine oil.Theresult shows that the increase of W/D causes the increase of heat transfer coefficient and resistanceforce of fluid flow. The heat transfer coefficient can be enhanced mainly within the length of ninetimes of inner diameter of tube for oil.In the range of experiment, the value of creteria to evaluatethe combined effect is between 1.13 and 1.59.
