  • The experiment mainly conducted the effect of two different structure diaphragm plates in the complex passages on heat transfer of turbine blade trailing edge. A laser bean irradiated the passages and a low-motion vidicon screened the particle-s flow in second pass passage. Comparison the flow was made among two kinds of diaphragm plates: rectangular diaphragm plates(RDP), 120° waved diaphragm plates(WDP) in the complex passages of turbine blade trailing edge. It was found that both these two diaphragm plates influence the flow, and the WDP has a special oscillation pulsating flow effect in the second passage. For WDP, the Re has fierceness influence. The oscillation effects enhance along with the Re change.
