 note = {A numerical procedure for solving the three dimensional viscous flow in a duet is deseribcd in this paper. The governing equations are parabolized according to boundary layer approximation such that the derivatives concerning physical quantities along the main flow direction are much smaller than those in the secondary flow direction. No assumption such as uncoupling of the longitudinal and eross flow pressure gradients is made for the pressure field. And also relaxed continuity equation is used, which allows constant source distributions in the radial direction. Assumed wall pressures are corrected by the Newton-Raphson method so as to reduce the source distributions to zero. Example calculations of the three dimensional flow field in a curved annulus and curved pipe are carried out. Typical secondary flow patterns are obtained for either case., 資料番号: NALSP0001009, レポート番号: NAL SP-1},
