abstract = "As low pressure turbine structure design more and more compact, the upstream wake on downstream cascade of periodic interference effect is more and more obvious, in this paper, based on the existing research, through the arrangement of uniform motion of cylindrical upstream cascade to generate periodic wake, analysis of the flow field of low pressure turbine in the condition with or without wake, and the results show that the upstream wake periodically makes the airflow velocity in the cascade passage present cyclical change, after the flow stability, found that various conditions on the back of the blade suction surface are produced separation bubble, but the size and thickness of the separation bubble in the condition with wake are smaller. Therefore, the upstream wakes have an obvious effect on inhibiting the separation of suction surface boundary layer. The upstream wakes also significantly increased the pressure at the cascade leading edge.",
