Asymptotic theory of flows for the near wake of an axisymmetric body

A solution in the form of asymptotic series is obtained for the problem about the near wake behind a thin cylinder in an laminar incompressible flow. To find the solution, we use the method of expansion into series of the solutions for the inner and outer portions of the flow. The influence of the circulation flow is not taken into account. The so-obtained solution is applicable only within a limited distance from the afterbody. Some essential differences are observed between the axisymmetric flow and the corresponding problem about the two-dimensional wake after a flat plate. © 2015, Pleiades Publishing, Ltd.
