Supersonic, Transverse Jet from a Rotating Ogive Cylinder in a Hypersonic Flow by Daniel L. McMaster PDF Summary

Book Description: Numerical simulations were performed for a supersonic jet issuing from a blunt-nosed ogive cylinder into a Mach 12 cross stream. All calculations employed the finite differenced, mass-averaged Navier Stokes equations with an algebraic eddy viscosity model for turbulence closure. One portion of the present investigation was focused on the numerical resolution requirement for the three-dimensional separated flow field around the non-rotating body. For this purpose, four solutions were obtained using mesh systems with different numbers of grid points and clustering. The secondary separated flow field structure was resolved with moderately increased grid density. The major portion of the present study was devoted to the simulation of the flow field around the identical configuration with the added complexity of rotating motion about the principal axis of the body. Numerical solutions over a wide range of angular velocities were obtained in the rotating frame of reference. The effects of rotation on the global flow field structure and especially the jet plume formation were examined through a comparative study from the viewpoint of a stationary observer. At the low angular velocity of interest, the effects of body rotation on the flow field structure were significant.
