Abstract: This paper develops a method of using a quasi-three-dimensional finite difference (blade to blade) flow program to predict deviation angle. The work discussed herein was accomplished in support of Contract NAS3-15324 with Lewis Research Center of NASA, Cleveland, Ohio. An appropriate approximation to the Kutta Condition is developed. Results are compared with experimental data from cascades including the effects of meridional velocity ratio and compressibility. Predictions are extended to cases with radius changes. In addition, the same program is used to predict optimum angle of attack for a compressor blade row.
