The windage torque on rotational walls has negative effect on the performance of the low pressure turbine. In this paper, three novel flow control concepts (FCCs) were proposed to reduce the windage torque within a turbine stator well, with upstream...

Windage Torque Reduction in Low-Pressure Turbine Cavities Part II: Experimental and Numerical Results. Journal of Turbomachinery, 146(6), Article 061005. https://doi.org/10.1115/1.4063876

Minimizing the losses within a low-pressure turbine (LPT) system is critical for the design of next-generation ultra-high bypass ratio aero-engines. The stator-well cavity windage torque can be a significant source of loss within the system, influenc...

As part of the drive towards achieving net-zero flight by 2050, the development of ultra-high bypass ratio engines will place greater importance on the efficiency of the low-pressure turbine. Stator-well cavities can be a significant source of loss w... Read More about Influence of swirl and ingress on windage losses in a low-pressure turbine stator-well cavity.
