On the Courant–Friedrichs–Lewy criterion of rotating grids in 2D vertical-axis wind turbine analysis
The Courant–Friedrichs–Lewy (CFL) criterion for the stability of numerical schemes is herein investigated at the conservative interface that divides rotating grids embedded within fixed grids. This issue is of specific interest to correctly assess the power coefficient and the energy production of vertical-axis wind turbines (VAWTs).
