| Summary: | Three-dimensional flow measurements using LDV system were obtained in the exit region of
a radial inflow turbine at an off-design operating condition. The measurements reveal a
complex flow pattern near the tip region at the rotor exit due to the interaction of the tip
clearance flow. The effect of the rotor on the exit flow field is observed in the proximity of
the rotor exit. Steady axisymmetric, compressible, turbulent flow computations with a two
equation turbulence model were performed using the PARC code for the meridional flow in
the radial turbine exit region. The computational results obtained in the meridional plane are
compared with the experimental results, which are correlated to the rotor blade rotation in
the exit region of the radial turbine. |
