At present, there are many numerical methods for calculating the laminar boundary layer. Among them, the finite difference method, the method of straight lines and the method of integral relations of A. A. Dorodnitsyn should be especially emphasized.

The paper considers the solution of the laminar boundary layer equations on a semi‑infinite body of revolution streamlined by a binary mixture of gases at zero angle of attack. In the flow and on the surface of the streamlined body a reaction of the type X₂ = 2X is possible. Basic equations and boundary conditions. Consider a high‑temperature boundary layer on a body of revolution with an axis having the direction of the velocity of the oncoming flow. The gas motion in this case is obviously axisymmetric and is completely determined by the flow pattern in the meridional plane.

Consider a flat laminar boundary layer in an incompressible fluid in the presence of a longitudinal pressure drop. We assume the physical characteristics of the fluid to be constant for all points of the flow field, and the flow parameters to be independent of time.
