Secondary and Leakage Flow Effects in High-SPeed Low-PrEssurE TurbiNes

Project description

Probing the aerodynamics of low-pressure turbines at high speeds

High-bypass ratio turbofans offer enormous potential to reduce noise and pollution of aviation. In the geared engine architecture, the low-pressure turbines operate at transonic exit Mach numbers and low-Reynolds numbers. There is a critical shortage of experimental data at these engine-like conditions and especially at transonic exit flow speeds. The EU-funded SPLEEN project aims to fill this gap by carrying out detailed flow measurements in two world-class turbine test rigs at the von Karman Institute for Fluid Dynamics. The focus is on the interaction of secondary air and leakage flows with mainstream flow and its impact on turbine performance and design.
