AbstractThe flowfield around a helicopter is generally very complicated. Unsteady flow regions where the dominant flow velocities ranging from the very slow to the transonic co-exist, cause computational difficulties for numerical schemes without pre-conditioning treatment. An efficient and robust all-speed scheme SLAU is incorporated into a moving overlapping grids approach and a new CFD code named rFlow (rotor Flow solver) is developed. Comparisons and validations of the new CFD code are performed and advantageous results are obtained. The capability of this new code is shown with samples of complicated flowfields around rotary wings.
