Abstract: | Turbulent Taylor vortex flow, which is contained between a rotating inner cylinder and a coaxial fixed outer cylinder with
fixed ends, is simulated by applying the development in Reynolds stress equations mold (RSM) of the micro-perturbation. This
resulted from the truncation error between the numerical solution and exact solution of the Reynolds stress equations. Based
on the numerical simulation results of the turbulent Taylor vortex flow, its characteristics such as the fluctuation of the
flow field, the precipitous drop of azimuthal velocity, the jet flow of radial velocity, the periodicity of axial velocity,
the wave periodicity of pressure distribution, the polarization of shear stress on the walls, and the turbulence intensity
in the jet region, are discussed. Comparing the pilot results measured by previous methods, the relative error of the characteristics
predicted by simulation is less than 30%.
