Abstract: Modern approaches to visualization and automatic identification of regions are discussed separation of three-dimensional boundary layers. The corresponding algorithms are implemented within the framework of the original LOTRAN software package, designed to calculate the position of the laminar-turbulent transition in boundary layers over surfaces of small curvature. Their work is demonstrated using two configurations: a swept wing and a prolate spheroid.

Keywords: laminar-turbulent transition, three-dimensional boundary layer, flow separation, separation line, reattachment line, surface friction field.
