Extract

In a technical note in the January 1963 Journal J. Dunham shows a method to determine the choked condition in a cylindrical ejector nozzle which in a simpler way leads to the same expression that has been derived by H. Pearson et al. of Rolls-Royce Ltd. Although Mr. Dunham states it is unnecessary to use the “maximum-discharge” principle, his derivation in the case of two streams in a common passage is, by the assumptions he makes, based on just this principle.
