DESCRIPTION:Abstract: \n\nOffshore wind turbines (OWTs) can access abundant
  offshore wind resources. These devices are trending toward larger sizes\,
  with the next-generation of turbines expected to be 15~20 MW\, becoming t
 he largest rotating machines ever constructed. Due to their massive size\,
  model-scale experiments in laboratories are essential for observing and m
 easuring dynamic response under the expected wind and wave conditions. How
 ever\, model-scale experiments are also subject to scaling laws to maintai
 n dynamic similitude between the model- and prototype-scale forces. Each d
 ynamic force must follow a distinct similitude law based on geometric scal
 e. Since OWTs are subject to multiple dynamic forces from wind\, waves\, a
 nd structure\, similitude distortions then arise when scaling with respect
  to a single similitude law. Real-time hybrid simulation (RTHS) is a numer
 ical-physical approach that partitions a prototype model into numerical an
 d physical models that interact via actuators and sensors in real time. Si
 nce RTHS can partition the system dynamics\, different similitude laws can
  be applied in the physical and numerical models\, thereby mitigating simi
 litude distortions. For example\, a single dynamic force can be scaled in 
 the laboratory at model scale\, which is then coupled with a full-scale nu
 merical model representing the remaining dynamic forces. The project goal 
 is to mitigate similitude distortions in model-scale experiments of OWTs s
 ubjected to wind and wave loading. The overarching objective is to assess 
 whether RTHS can mitigate similitude distortions across hydrodynamics\, ae
 rodynamics\, and structural dynamics in OWT applications when an OWT is pa
 rtitioned into model-scale physical hydrodynamics and the other full-scale
  numerical dynamics\, referred to as hydro-RTHS. Results show that hydro-R
 THS can account for motions and forces induced by nonlinear waves in the g
 lobal response of OWTs. Hydro-RTHS can provide unique experimental dataset
 s for structures subjected to multiple dynamic forces\, accounting for phy
 sical wave-structure interaction effects while maintaining similitude at t
 he model scale.
