Finite difference schemes for the three-dimensional heat conduction equation and the unsteady Navier-Stokes equations in polar coordinates are developed. The schemes enjoy second-order accuracy in time and fourth-order accuracy in space and unconditionally stable ADI methods for their solution are discussed. Numerical experiments indicate that the methods retain their accuracy even close to the polar singularity.
