A Numerical Study on the Development of Self-Similarity in a Wind Turbine Wake Using an Improved Pseudo-Spectral Large-Eddy Simulation Solver
Large-eddy simulation (LES) is performed to investigate self-similarity in a wind turbine wake flow.The turbine is represented using an actuator line model in a pseudo-spectral method-based solver.A new hybrid approach of smoothed pseudo-spectral method and finite-difference method (sPSMFDM) is proposed to alleviate the Gibbs phenomenon caused by t
