摘　　要：分块隐式有限体积方法求解不可压旋转粘性流动孙自祥，吴玉林，董曾南，薛敦松，胡泽明（石油大学机电系北京１０００８３，清华大学水利水电系北京１０００８４）关键词分块隐式有限体积方法，旋转粘性流动计算１引言旋转流动是常见的工程问题之一。旋转流动之所以复杂，...In this paper, the Block Implicit Finite Volume Method (BLIFV) is extended for calculation of three dimensional incompressible rotating flows in body-fitted coordinate systems.Computations of the developing laminar flows in a rotating duct have been conducted for Reynolds number Re=10￣1000 and rotation number Ro = 0 ￣ 1. Results show that the strength of secondary flow increases with Re or Ro; And at Re=100 and Ro=0.5, the TaylorProudman regime appears in the channal, which agrees well with that from Ref.[2,3,4].
