Summary

A detailed set of time-dependent, vane/blade aerodynamic interaction simulations was compiled using the VBI Navier-Stokes analysis code for the Purdue low speed turbine research rig. The simulations depict the time-dependent features of this complicated aerodynamic problem both with and without hub leakage flow. Decomposition of the data depicts several key features of the interactions between the leakage flow, and primary and secondary flow features through the blade passage. Animations of the time-dependent simulations improve our understanding of this problem and lend insight for measured data. Future efforts will concentrate on correlating test and prediction data more thoroughly and examining other features of this complex flow.
