This book was released on 1983 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unsteady, compressible, Reynolds-averaged Navier-Stokes equations were solved for the flow field about an external compression axi-symmetric inlet with a length to diameter ratio, L/D = 15.88, at Mach 2.0 and a Reynolds number based on diameter, ReD = 2.36 times 10 to the 6th power, operating in the near-critical and subcritical flow regimes. The near-critical solution reached a stable steady state while the subcritical solutions attained an unstable bounded oscillatory state, characterized by large amplitude pressure oscillations and traveling shock waves. This phenomenon is a result of a shear layer instability combined with a closed-loop feedback of reflected disturbances and the naturally occurring self-sustained oscillations are commonly known as buzz. Numerical results are given in terms of Mach contours, velocity field plots, pressure-time traces at selected stations, as well as mass flux and other mass-averaged quantities along the duct length. Comparison with experiment is also given. (Author).

This book was released on 1974 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hypersonic flow field over a concave shape has been investigated by numerically solving the unsteady Navier-Stokes equations. Calculations were performed at a freestream Mach number of 10 and a Reynolds number based on freestream properties and the forebody radius of 333. A fully attached high frequency oscillatory flow field was found to exist over the entire surface. This type of oscillation is unique since experimentally observed oscillatory flows about concave shapes have contained separated regions. The nature of the oscillation, its effect on surface properties and the postulated origin of the oscillation, is discussed. Specifically, the flow field appears to be hydrodynamically unstable which results in an oscillatory variation of the flow downstream of the forebody pressure minimum. The resultant temporal variations of the surface pressure and heat transfer are large in the region of the shock inflection point.
