Numerical solution of turbulent Taylor-vortex flow
AbstractThe numerical solution of mean turbulent Taylor-vortex flow is shown. The azimuthal-invariant, cylindrical, Navier-Stokes equations are solved to steady-state for the case of inner cylinder rotation with radius ratio 0.5 and Taylor cell wavelength 2.3. Closure is obtained via a Prandtl-Van Driest turbulence model. Subject to no-slip conditions at radial boundaries and periodic conditions at axial boundaries, the turbulent solution was obtained for a critical Taylor number multiple of 700. The vorticity-velocity method relies on a second-order accurate alternating-direction implicit (ADI) scheme with logarithmic grid clustering. Convective terms are differenced by a hybrid method that is central-preferred/upwind. Azimuthal velocity and wall shear stress are compared to the experiments of Taylor.
