An energy preserving time integration method for gyric systems: Development of the offshore wind energy simulation toolkit Conference Paper uri icon

abstract

  • This paper presents an overview on the development of a finite element design tool for offshore vertical-axis wind turbines (VAWTs). VAWT configurations possess desirable characteristics for large offshore wind applications, and motivation for considering this configuration is discussed. The modular and flexible finite element framework of the Offshore Wind ENergy Simulation (OWENS) toolkit is presented. This paper also presents an energy preserving time integration method that has been implemented into OWENS. A previously developed time integration method has been extended to rotational systems. The method utilizes system energy to construct an unconditionally stable integration scheme. Consequently, for conservative systems energy is preserved regardless of time step size. The integration method is demonstrated on a representative VAWT configuration with aerodynamic and platform effects, and compared to another popular integration method. Overall, desirable properties of the energy preserving integration scheme are observed.
