适用范围

ESDU 94015 presents charts for 20 cowls of the distributions computed from finite difference solutions to the Euler equations for inviscid compressible flow. Computed shock waves are smeared over a few mesh cells which should give correct shock pressure jumps. The results are shown as functions of freestream Mach number and mass flow ratio. Data are presented for the same cowls and flow conditions as in ESDU 94014 which gives corresponding values of coefficients of wave drag@ pre-entry force and forecowl pressure force. Sixteen cowls have NACA 1-series external profile@ with differing combinations of diameter ratio and fineness ratio. The remaining four have fixed diameter ratio and fineness ratio but external profiles that differ systematically from the NACA 1-series profile.
