Steady axisymmetric flows in disk systems are investigated numerically. Steady states are calculated by adapting a time-stepping pseudo-spectral code to carry out Newton's method. A self-similar solution is shown to exist surrounding the axis, with a recirculating zone near the end-wall. Between these two zones is a pseudo-similar region where velocity profiles are homothetic.
