Discussion: “Generation of Oscillating Jets” (Favre-Marinet, M., Binder, G., and Hac, Te. V., 1981, ASME J. Fluids Eng., 103, pp. 609–614)

Abstract

Author's Closure Mr. McBride's comments are appreciated. Most of the points made are accepted, however, the suggestion that the six zone convention be replaced by a single zone convention is not attractive. The six zone convention was adopted because it yields smooth, well behaved, yet uniformly sensitive relationships between the measured pressure ratios and the parameters sought. Single zone correlations could not cover the same range of probe orientations without possessing singularities, since there is no single pressure difference available as a denominator, which does not go to zero somewhere in the operating range. An attempt was made to fit the entire correlation surfaces with splined polynomials, however, better accuracy and speed were achieved with a bi-cubic interpolation in the region of the operating point.
