Numerically investigate the effects of freestream turbulence on dynamics of a low-pressure turbine stage
Based on SSTturbulence model coupled with Langtry-Menter transition model
a three-dimensional
vicous
steady CFDanalysis was performed for investigating the effects of freestream turbulence on the dynamics of a LPturbine stage at different Reynolds numbers.From the CFDprediction results
the rules of freestream turbulence effects on the flow mechanics on blade suction surface
and on Reynolds number effects on this LPturbine stage efficiency were obtained.Also
based on a kind of loss separation method
freesteam turbulence effects on the flow loss components
such as the profile loss
the endwall boundary loss
and the tip clearance loss inside this LPturbine stage were further distinguished.
