文摘

2D CFD models cannot capture blade tip and strut effects. 3D CFD models can now accurately capture turbine power output. k-ω SST turbulence models provide the closest agreement with experimental results. Transition flow modeling is computationally demanding and only increases simulation accuracy at high rotational rates. BSL-RSM and k-ω SST Wall Function models poorly simulate power output.
