High Resolution Numerical Method
A recent growing interest in Urban Air Mobility (UAM) worldwide has led to the demand for physical analysis of the aerodynamic performance and aeroacoustic characteristics of electric Vertical Take-Off and Landing(eVTOL) rotorcraft. In UAM eVTOL rotorcraft, the smaller vortices generated from multiple propulsors complicately interact with lifting surfaces such as wings, fuselage, and propellers. Therefore, for the accurate performance and noise prediction of UAM eVTOL rotorcraft, vortices should be preserved with few dissipation, and their interactions must be modeled precisely. This requires a numerical algorithm with a more refined resolution than allowed by conventional schemes. eMLP-VC (enhanced Multi-dimensional Limiting Process for Vorticity Conservation) exhibits superior resolution, numerical stability, and computational time efficiency compared to the conventional high-order schemes.
