摘要
Abstract
A numerical method based on solutions of 3-D Euler/N-S equations is used for calculating the rotor flowfield in hover. Jameson central scheme, Van Leer scheme and AUSM scheme are implemented for spatial discretisation, and Van Albada limiter is also applied. Simultaneously, overset grids are adopted. Hole-Map method is utilized to identify intergrid boundary points (IGBPs). Furthermore, aiming at identification issue of donor elements, Inverse-Map method is implemented. Finally, blade surface pressure distributions derived from numerical simulation are validated compared with the experimental data. Results show that all the schemes mentioned above can accurately simulate the rotor flowfield.关键词
