THE INCOMPRESSIBLE LAMINAR AXISYMMETRIC WAKE

Abstract

The memorandum considers the asymptotic development of the axisymmetric incompressible wake far behind a long, thin cylinder. This is the axisymmetric analogue of the classical two-dimensional flat-plate problem; however, the resulting solution is applicable to a wider class of axisymmetric bodies. In Section II an asymptotic expansion in inverse powers of the axial distance downstream of the cylinder is attempted. In Section III the axisymmetric problem is reformulated, and it is shown that as in the two- dimensional problem the cause of the breakdown of the solution given in Section II is the existence of a logarithmic term in the second-order approximation.
