Abstract: In a high bypass ratio aircraft engine, the high-pressure and low-pressure turbines are connected by an intermediate turbine duct (ITD). The aerodynamic performance of the ITD is affected by the incoming flow from the ...

Abstract: The integration design of the intermediate turbine ducts (ITDs) with the first row of the low-pressure turbine vane can significantly reduce the length of the turbine section, thus reducing the weight and drag of the ...

Abstract: In high bypass ratio engines, the flow exits the interturbine duct (ITD) and enters the low-pressure (LP) turbine. This paper aims to understand the effects of the boundary layer at the exit of ITD on the endwall secondary ...
