    Abstract

    The single slanted hot-wire technique has been used extensively as a method for measuring three velocity components in turbomachinery applications. The cross-flow orientation of probes with respect to the mean flow in rotating machinery render multiplewire probes subject to detrimental prong interference effects. As a result, the single slanted hot-wire technique is often preferred. Typical data reduction techniques solve a set of nonlinear equations determined by curve fits to calibration data. A new method is proposed which utilizes a look-up table method applied to a simulated triple wire sensor. Using experimental data collected from a multi-stage research compressor, results using these two data processing techniques are compared. Consideration is given to the experimental error which accompanies each data reduction process. Specific discussion regarding corrections for temperature and density changes present in a multistage compressor application is also included.
