Abstract:In this paper, a hybrid Cartesian grid method is used to simulate the flows around the S809 airfoil and Phase VI blade. In this method, the body-fitted structured grid is used near the body surface to obtain required viscous near-body mesh, and the Cartesian grid is generated in the left region. To exchange the data between two grids, the donor cell searching technique is adopted. In order to remove the rigidity of equations at low-speed, the low-speed precondition is used to simulate the wind turbine. For the simulation of Phase VI blade with the axial flow conditions, the rotating coordinate frame is adopted in the present hybrid Cartesian grid method. Furthermore, a local Cartesian grid refining treatment is successfully used to capture the wake vortexes. The results show that the developed low-speed solver on the hybrid Cartesian grid can accurately simulate the axial flow field, and successfully capture the blade tip and root vortexes. © 2019, Editorial Board of Acta Energiae Solaris Sinica.
