Abstract
A wide variety of models have been proposed to assess the effect of vortex shedding loads on the dynamics of bluff bodies. To the best of the authors' knowledge, a critical review of such models applied to wind turbine towers has not been carried out. A comparison is made in the present work of three well-known models, ranging from the simplest type A or forced system model, through type B or fluidelastic system model, to type C or coupled system model. Time-marching simulations are performed using classical modal analysis of an isolated wind turbine tapered tower subjected to a sheared and turbulent wind profile. Tower dynamics and vortex shedding-induced loads are limited to the cross-flow direction. Maximum tower top deflections are presented in the comparison, and a sensitivity analysis to type C parameters is performed. The results provide a comparison of the qualitative differences of the different modelling levels applied to a wind turbine tower. Further development of type C models seems to be a promising path to be used in the wind energy community to assess vortex-induced vibrations of wind turbine towers.
