英文摘要 | Boundary layer separation and reattachment is often an unavoidable feature of low pressure (LP) turbine, one of the main causes of this phenomenon is the high altitude low Reynolds number experienced by the modern LP turbine stage in aero-engine. Although an excellent turbine airfoil design can avoid flow separation on certain extent, but within flight envelope, LP turbine's characteristic Reynolds number may varied greatly, so it will be still under the risk of the presence of separation bubble. In this two parts paper a new concept of slotted-blade was raised to testify the gain of the blade slotting. A high aerodynamic loading LP turbine blade IET-LPTA was under investigated with different Reynolds number. Computational results reveal that the blade slotting could be a way of choice to suppress separation bubble and reduce profile loss under the condition of low Reynolds number, although its position and geometry need to be further investigated. |
