タイトル（掲載誌）航空宇宙技術研究所特別資料 = Special Publication of National Aerospace Laboratory SP-14
一般注記The three-dimensional Navier-Stokes equations are solved to analyze the flowfield around a blade tip of a hovering rotor. The eddy viscosity is calculated by employing the Baldwin-Lomax zero-equation turbulence model and the q-w two-equation turbulence model developed by Coakley. An implicit finite-difference method is used to solve the equations and the algebraic method is adopted to generate the grids. The effect of wake outside of the grid is taken into calculation by correcting the equivalent geometric angle of attack along the blade radius. Its value is estimated by using prescribed vortex lattice method (VLM) or Local Circulation Method (LCM). The pressure distribution on blade surface predicted by the present method are similar to other theoretical results and are in reasonable agreement with the experimental data. In addition, the present results are compared with the results calculated by our Euler code. In transonic case, some differences are shown in these results.
