This study numerically examines hydrodynamic characteristics and instabilities of oscillatory flows over cylindrical structures and plane boundary at low Reynolds numbers, where flows are laminar or on transition to turbulence. Two-dimensional and threedimensional direct numerical simulations and Floquet analysis have been used to investigate the influence of plane boundary proximity on 2-D flow regimes (Chapter 3) and Honji instability (Chapter 4) of oscillatory flow around a circular cylinder, and oscillatory flow around an isolated cylindrical structure of circular (Chapter 5) and square cross-section (Chapter 6).
