摘要
A method for computation of three-dimensional turbulent flows in mixing units of bypass turbojet engines in which lobe extensions are used to intensify mixing is suggested. The flow upstream of the lobe extension exit is subdivided into a potential core and a boundary layer. The potential flow is computed by the Boundary Integral Equations Method, and the viscous flow is calculated by an integral method for three-dimensional turbulent boundary layer. The flow in the mixing chamber is computed by the parabolic Reynolds equations and a one-parametric turbulence model. Flows in a set of mixing devices have been computed. The results are shown to be in agreement with experimental data.
