Numerical Experiments on Boundary-Layer Receptivity, and near the leading edge of the plate is an integral part of the solution algorithm which requires no special treatment; thus allowing for the flow field in this region to be studied in detail. An incident plane sound wave is imposed in the free-stream flow and the receptivity of the boundary laye

The Linear Stability of the Incompressible Boundary Layer on an Ellipsoid at Six Degrees Incidence, the Orr-Sommerfeld equation was used to compute local amplification rates for both streamwise and cross flow instabilities. At six degree incidence, it was found that the spatial growth of unstable waves is essentially governed by two dimensional instability, modified by the presence of cross flow.

On Short-Scale Inviscid Instabilities in the Flow Past Surface-Mounted Obstacles,y years. These effects include most notably separation and instability, often leading to transition to turbulence. Two main reasons possible for such transition have been suggested: either the sur-distortion produces in effect a locally separated shear flow which is susceptable to inviscid instabili

Wave Phenomena in a High Reynolds Number Compressible Boundary Layer,cal simulations are conducted by solving the laminar, two-dimensional, compressible Navier-Stokes equations over a flat plate with a fluctuating disturbance generated at the inflow. The primary objectives of this work are to study the nonlinear growth and distortion of the unstable waves and also to

Instability of Time-Periodic Flows,tler vortices are described in detail. The simplest flow where this type of instability can occur is that due to the torsional oscillations of an infinitely long circular cylinder. For more complicated spatially varying time-periodic flows a similar type of instability can occur and is spatially loc

Stability Characteristics of Some Oscillatory Flows-Poiseuille, Ekman and Films, of this study is to learn how time periodic oscillations modify the stability characteristics of steady flows. It is useful to understand such effects because small amplitude time periodic modulations of a flow may be a way to either enhance or delay mixing processes if the modulations destabilize
