Galerkin Spectral Method for the Vorticity and Stream Function Equations

A Galerkin?Legendre spectral method for the solution of the vorticity and stream function equations in uncoupled form under no-slip conditions in a square domain is presented which fully exploits the separation of variables in the two elliptic problems, benefits from a nonsingular influence matrix, and is able to solve the singular driven cavity problem (modulo Gibbs' phenomenon) even without regularizing the boundary condition at the corners.
