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).

The purpose of this project was to develop a numerical method capable of calculating the laminar flow about a two dimensional accelerating body using the incompressible Navier-Stokes equations. This problem arises in the calculation of the dynamic stall of an airfoil and in the calculation of pitching and heaving stability derivatives for an isolated airfoil. It is also a first step toward solving the three dimensional flow about a complete wing undergoing arbitrary motion at high angles of attack, including departure, spin, and post-stall maneuvers. Numerical calculations to date have not been satisfactory. Test cases presented are Stoke's first problem, a circular cylinder translating at a Reynold's number of 20, and a rotating stationary circular cylinder. Keywords include: Aerodynamics, Airfoils, Difference equations, Navier Stokes equations.

Two-Dimensional Separated Flows provides a systematic presentation of the theory of separated flow around bodies. The main classes of aerodynamic problems of plane-parallel flow around bodies are described, and the steady aerodynamic, unsteady aerodynamic, and statistical characteristics of a trailing wake are determined. Numerical methods based on the synthesis of models for non-viscous incompressible flow and boundary layer, algorithms, examples, and systematic comparisons are presented. The book also includes numerical results for the problem of separated flow around fixed, oscillating, and rotating cylinders, in addition to results for separated flow around an aerofoil over a wide range of angles. Two-Dimensional Separated Flows will benefit researchers and students studying aerodynamics, aircraft dynamics, aeroelasticity, and the aerodynamics of building structures.
