Flow separation and the nonuniqueness of solutions to axisymmetric boundary-layer equations. (Q1975090)

The paper is devoted to numerical solution of time-independent two-dimensional equations of axisymmetric laminar incompressible boundary-layer flow under unfavorable pressure gradient. In the case of separated flow past a body, the solution is shown to be generally nonunique downstream of the zero-friction point. The numerical solution can be continued either downstream of the separation point or downstream of the reattachment point. Examples illustrate the construction of such solutions.
