Locally Refined POD‐Galerkin Based Reduced Order Modelling for Fluid‐Structure Interaction Problems of Wind Turbines

The goal of this PhD project is to develop a new ROM approach to the FSI problem applicable to moving and/or deforming solid boundary and then applied it to the Vertical Axis Wind Turbine (VAWT) structure analysis in or‐ der to improve the wind turbine fluid‐structure interaction analysis method regarding both the simulation efficiency and accuracy. A new and novel lo‐ cal refinement strategy on the ROM method is proposed in order to balance the increase in time cost and accuracy. Moreover, this strategy includes elas‐ tic behaviour of solid domains, thus increases the capability of the approach to solve FSI problems with large moving interfaces between the rigid body and the fluid.
