The criterion of separation of incompressible laminar boundary layer flow over an axially symmetric body (Q1107384)

The separation criterion of axially symmetric incompressible laminar flow in close agreement on the separation point of the sphere with experimental data is presented by correlating to two-dimensional flow by the successive solution of a boundary layer equation. Applying the presented criterion and analysis, the location and laminar separation boundary layer characteristics of incompressible axisymmetric as well as two-dimensional flow can be accurately predicted using external inviscid velocity distribution only and not by referring to boundary layer flow.
