THIS THESIS REFERS TO THE STUDY OF SOME FORMS OF OSCILLATORY BOUNDARY LAYER FLOW. THIS FLOW IS DUE EITHER TO THE OSCILLATIONS OF A BODY IMMERSED INTO AN UNBOUNDED VISCOUS FLUID (EXTERNAL FLOWS) ON TO THE OSCILLATIONS OF A VISCOUS FLUID THAT IS BOUNDED IN A REGION (INTERNAL FLOWS).

Experimental analysis of flow and turbulence characteristics in oscillatory boundary layers from LDV measurements
The oscillatory boundary layer represents a particular case of unsteady wall-bounded flows in which fluid particles follow a periodic sinusoidal motion. Unlike steady boundary layer flows, the flow regime and bed roughness character of oscillatory flows change in time during the oscillation, a …

The harmonic excitation of a cylindrical bubble pinned to a plane surface: flow field and oscillation dynamics
… bubble pinned to rigid substrate to an imposed oscillatory far field pressure, and subsequently describe the resulting steady flow that results in the fluid in the exterior of such a bubble. We first derive an analytical expression for the allowable shape oscillations of a two-dimensional bubble …

CFD study of hydrodynamic signal perception by fish using the lateral line system
… is developed for the dipole induced, oscillatory, boundary layer velocity profile over the surface of a fish. An analytic solution is developed for the case when the surface is a wall, and is accurate at points of maximal surface tangential velocity. Results indicate that the flow …

A CONTINUUM MIXTURE THEORY APPROACH TO SEDIMENT TRANSPORT WITH APPLICATION TO TURBULENT OSCILLATORY BOUNDARY LAYERS
… from a number of turbulence models for oscillatory, turbulent boundary layer flow containing suspended sediment. A review is given of previous work that has applied continuum mixture theories to the field of sediment transport. Turbulent averaged forms of the mixture equations are …
