SIMULATION AND MITIGATION OF VORTEX INDUCED VIBRATIONS BY MEANS OF HIGH FIDELITY FSI SIMULATION AND ADVANCED MESH MORPHING
In this study we face a complex and challenging problem: the control of Vortex Induced Vibrations (VIV). The fluid structure interactions involved poses two kind of problems. First of all skills of structural and fluid analysts are needed and a proper interaction of experts is a paramount to be successful. Furthermore, an accurate modelling requires state of the art tools for the computational fluid dynamics and for the computational structural mechanics to be combined together.
Advanced mesh morphing enabled by radial basis function is a key enabler in this field: it allows to create an efficient and fast workflow for a strong coupled FSI analysis and, at the same time, to make such workflow parametric with respect to the design so to have, at the end, the ability to steer the design toward the desired VIV behaviour. We adopt structural modes embedding to make the fluid solution “flexible”. The dynamic features of the system are computed with the FEA solver Ansys Mechanical, embedded in the fluid solver Ansys Fluent by means of the mesh morphing software RBF Morph. The shape parametrisation technology offered by RBF Morph is then used to steer the design. The method is demonstrated for a specific application: the design of a thermowell.
