Consideration is given to separation-free plane flow in a boundary layer developing on a smooth diffuser wall under the action of a pressure gradient p(x), where both quantities dp/dx and d2p/dx2 are positive (adverse pressure gradient). The adverse pressure gradient arose in a diffuser with plane walls (experiment F0141A). The results of numerical calculations of flow with a nonzero pressure gradient in the boundary layer of an incompressible liquid with the use of the near-wall k–ε model of turbulence are given. A comparison of the basic characteristics of flow with tested experimental and theoretical data is made.
