In a two-dimensional flow, an exact analytical form is obtained for Prandtl Meyer waves, so the basis of the characteristic method is well established. But in three dimensional axially symmetric flow, no exact solution exists for such expansion waves. In this report, a new type of similar solution of linearized flow is compared with the result by the characteristic method. This result is used to study the periodic structure of an exhaust jet.
