Flow characteristics in a rotor-stator cavity with cooling air inlet at low radius
cooling system rotor-stator system flow characteristics pressure distribution resistance coefficient
2015/5/12
Experiments were conducted on a typical rotor-stator system where air entered through an annular slot at low radius and flowed out of the cavity axially through a rim seal between the rotor and the st...
Coupled thermal-fluid analysis with flowpath-cavity interaction in a gas turbine engine
CFD FEA Compressor Engine
