1. Modelo hidro-elástico para simular as vibrações induzidas por vórtices em cabos submersos. / Hidro-elastic model to stimulate vortex-induced vibrations in submerged cables.
The present work proposes a qualitative numerical study of a hydro-elastic model in order to simulate vortex-induced vibrations in submerged cables. The model is composed of a coupled system of equations describing the structure and the fluid. The structure is modeled through a classical elastic oscillator and discretized using a lumped mass approach. The fl

2. High Reynolds number oscillations of a circular cylinder
This paper concerns the numerical simulation of the flow around an oscillating circular cylinder, which moves with constant velocity in a quiescent Newtonian fluid with constant properties. For each time step of the simulation a number of discrete Lamb vortices is placed close to the body surface; the intensity of each of these is determined such as to satis

3. The influence of stable stratification on the transition to turbulence in a temporal mixing layer
The transition to turbulence in a stably stratified flow is a problem of considerable interest in fluid dynamics with applications in both geophysical sciences and engineering. This transition is controlled by competition between the vertical shear of the base flow and the buoyancy forces due to the density stratification. The present work investigates numer
