All rights reserved.Solving a flow around a rotor via CFD techniques is still very expensive due to the complex behaviours of the air flow around a rotor. This study attempts to analyze the S-76 main rotor configuration with swept-tapered tip in the hover position. The SU2 software is utilized with an anisotropic adaptive mesh refinement process provided by pyAMG software in this respect. Thoroughly capture of tip vortices is aimed with a significant reduction in the number of nodes compared to studies in the literature, taking advantage of anisotropic mesh adaptation process. Three different Euler simulations are designed to study either the effects of Mach and entropy sensor functions and also the effects of different anisotropy levels. The results are examined in different aspects.
