Book Description
The numerical experiments, carried out through the use of a pressure-velocity coupled method to solve the Favre Averaged Navier-Stokes equations, on steady and sinusoidally oscillating flows at five different Keluegan-Carpenter numbers, and three periodicity levels are described. A second-order in time, second-order in space, second-level predictor-corrector finite difference scheme has been used. The solutions were solved by the CFD-ACE program from the CFD Research Corporation. The analysis has produced in-line force coefficients comparable to those obtained experimentally for sinusoidally-oscillating flows.

Book Description
A comprehensive numerical model has been developed to investigate the characteristics of flow about a circular cylinder undergoing synchronized transverse oscillations. The model is based on the rediscretization of the shear layers, wake-boundary-layer interaction, and the dissipation of vorticity. The forces acting on the cylinder, rate of vorticity flux, Strouhal number, cylinder response, oscillations of the stagnation and separation points, longitudinal and transverse spacing of the vortices, and the base pressure have been calculated and shown to be in conformity with those obtained experimentally. The model has been used to predict the characteristics of hydroelastic oscillations of a cylinder in the range of synchronization. The numerical experiments shed considerable light on the interaction between the fluid motion in the wake and the dynamics of the body. An extensive sensitivity analysis has been carried out to determine the stability of all the parameters and hence the stability of the numerical model itself. (Author).
