Book Description
Flow over elliptic cylinders can be considered prototypical of flow over a range of bluff bodies since the geometry allows one to study the effect of both thickness and angle-of-attack on the flow field. Therefore a careful study of this flow should provide valuable insight into the phenomenon of unsteady separation and the structure of bluff body wakes. With this in mind, a spectral collocation technique has been developed to simulate the three-dimensional incompressible flow over elliptic cylinders and unlike spectral element and spectral multi-domain techniques, here the flow is solved in a single domain. The equations are discretized on a body fitted elliptic cylindrical grid and properties of the metric associated with this coordinate system are used to solve the governing equations in an efficient manner. Other key issues including the inflow and outflow boundary conditions and time-discretization are discussed in detail with the hope that this will facilitate future simulations of simdar flows.

Book Description
Unsteady algorithms Fully Implicit and Crank Nicholson were developed for body fitted curvilinear coordinate system to study the incompressible flow over two-dimensional ellipses. In addition, explicit cyclic boundary condition was implemented to facilitate analysis of vortex shedding. Unsteady flow over circular cylinders was simulated for different Reynolds numbers and compared with experimental data. Flow over ellipses was simulated to study the effect of aspect ratio on drag coefficient. It was observed that the drag coefficient increased as the aspect ratio increased reaching an asymptotic value as the ellipse approached a flat plate.

Book Description
This book discusses the subject of wave/current flow around a cylinder, the forces induced on the cylinder by the flow, and the vibration pattern of slender structures in a marine environment.The primary aim of the book is to describe the flow pattern and the resulting load which develops when waves or current meet a cylinder. Attention is paid to the special case of a circular cylinder. The development in the forces is related to the various flow patterns and is discussed in detail. Regular as well as irregular waves are considered, and special cases like wall proximities (pipelines) are also investigated.The book is intended for MSc students with some experience in basic fluid mechanics and for PhD students.
