Abstract

The performance of the dual time method is improved by means of an inner iteration based on an LU-SGS driven FAS multigrid method, and by using the same LU-SGS method in a time-accurate mode to provide a starting solution for each dual time step. This hybrid scheme is applied to an aerofoil undergoing dynamic stall, whereby considerable performance improvements are demonstrated over the original dual time method.
