| 摘 要： | In order to make the numerical calculation of viscous flows more convenient for theflows in channtel with comphicated profile governing equations expressed in the arbitrarycurvilinear coordinates were derived by means of Favre density-weighted averaged method,and a turbulent model with effect of curvature modyification was also derived.Thenumerical calculation of laminar and turbulent flows in divergent curved channels wascarried out by means of parabolized computation method.The calculating results were usedto analyze and investigate the aerodynannic performance of stator cascades in compressorspreliminarily.
