Abstract:

A fully discrete mixed Legendre-spherical harmonic spectral method was proposed for the Navier-Stokes equations in a domain between two concentric balls. Legendre orthogonal approximation is used in the radial direction, and spherical harmonic orthogonal approximation in other directions. The forward difference quotient is used for time derivative. Numerical results show efficiency of this approach.

Key words: spectral method, Navier-Stokes Equations, domain between two concentric balls
