Investigation on the Flow Field over a Rotor using Overset-grid Method

摘要

In order to provide support for the mechanism research of the flow field over a rotor and the design of thernblade of a rotor, the flow field over a modal rotor has been simulated by using overset-grid method. And thernvalidation of the computation result has been identified by comparing with the experiment data. Somerncharacteristics of the flow field in hover conditions with different collective angles and different rotationrnspeeds have been investigated in this paper, such as velocity vectors, streamlines vorticities and so on. Thernend of the paper gives the conclusions.
