| 摘 要： | IntroductionSeveral investigations for highly loaded turbineblades have been tried in order to increase the turbineloading and the turbine inlet tempefature["']. Thehighly loaded tUrbine blades are able to reduce both thenumber of blades and the stages. Thus, the highly loadedturbine cascades can reduce the weight and theproduction cost of turbojet-engines. However, in order toachieve the high loading of the turbine blade, the highturning angle is necessmp. As the consequence, the strongt…

| Abstract: | The highly loaded turbine blades are able to reduce both the number of blades and the stages of turbojet-engines. In this study, PIV(Particle Image Velocimetry) method is used for the measurements of the secondary flow in ultra-highly loaded turbine blade cascades. The results obtained by the PIV method clearly show the complicated behavior of the secondary flow in the cascade. The horseshoe vortex and the passage vortex are observed inside the cascade. Moreover, the wake generated by the accumulation of the low energy fluid by the passage vortex near the suction side and that discharged toward downstream of the trailing edge has been recognized. |
