【 摘 要 】

In this paper, known probabilistic methods for estimating the thickness of the boundary layer of a two-dimensional laminar flow of viscous incompressible fluid are extended to three-dimensional laminar flows of a viscous compressible medium. Their applicability to the problems of boundary-layer stability is studied with the $\mathrm{LOTRAN}3$ software package, which allows us to compute the position of laminar-turbulent transition in three-dimensional aerodynamic configurations.
