Abstract: This paper presents an experimental and computational study of the effect of severe inlet temperature distortion (hot streaks) on the efficiency of the MT1 HP turbine, which is a highlyloaded unshrouded transonic design. ...

Abstract: Modern lean burn combustors now employ aggressive swirlers to enhance fuelair mixing and improve flame stability. The flow at combustor exit can therefore have high residual swirl. A good deal of research concerning the ...

Abstract: This paper presents an experimental and computational study of the effect of inlet swirl on the efficiency of a transonic turbine stage. The efficiency penalty is approximately 1%, but it is argued that this could be ...
