Keywords： Flow visualization,Taylor-Couette flow,Taylor vortices,numerical model

Abstract：This work uses the incense as the trace of flow to perform flow visualization of Taylor-Couette flow.The test section was made of a rotational inner cylinder and a stationary outer cylinder.Two modes of inner cylinder were employed.One had a smooth wall,and the other had an annular ribbed wall.Clear and complete Taylor vortices were investigated in both smooth and ribbed wall of co-axial rotating cylinder.Besides,a stesdy-state,axis-symmetrical model was provided to simulate the present flow field.The Toylor vortices could be also successfully predicted.However,the assumption of steady-state

Flow might reduce some flow perturbations,resulting in an over-predicted critical Taylor number.A transient simulation is suggested to be performed in the future.
