The numerical simulation calculation of turbulent flow in 90° elbow pipe with square cross_section has been carried out. The formation and development of the second flow can be seen clearly through the computation result. The result is satisfied compared with Humphrey′s experiment; and the realizable k-ε equation is proved a good solution to the computation.
