Abstract: The aerodynamic performance of a typical sail in a twisted wind was numerically studied by solving NavierStokes equations, and the effects of various factors on the sail’s aerodynamic performance were discussed. Valuable theoretical references of sailing manipulation in a complex wind field were provided.
