Analysis the different rotational velocity impact on eccentric vortex inside of the Fanwing

摘要

In this article, a numerical simulation method for the unsteady fanwing flowfield has been established byrnsolving the N-S equations , based on the eccentric vortex exist inside fanwing. The aerodynamicrncharacteristics of funwing under different state have been numerical simulation by using this method. Therneccentric vortex inside fanwing have been discussed through the calculation results.
