並列タイトル等An Implicit Time-Marching Method for the Three-Dimensional Navier-Stokes Equations of Contravariant Velocity Components
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-9
一般注記The implicit time-marching finite-difference method for solving the three-dimensional compressible Euler equations developed by the authors is extended to the Navier-Stokes equations. The distinctive features of this method are to make use of the momentum equations of contravariant velocities instead of the physical velocities, and to be able to treat the periodic boundary condition for the 3-D impeller flow easily. These equations can be solved by using the same techniques as the Euler equations, such as the delta-form approximate factorization, diagonalization and upstreaming. In addition to them, a simplified TVD scheme by the authors is applied to the present method in order to capture strong shock waves clearly. Finally, the computed results of the 3-D flow through a transonic compressor rotor with tip clearance are shown.
