Аннотация:https://iopscience.iop.org/article/10.1088/1742-6596/1705/1/012011 For the classical formulation of the Jeffery-Hamel problem of the stationary flows of a viscous incompressible fluid in a plane diffuser the solutions are found. The bifurcation of the basic single-mode flow into flows containing sectors of flow and outflow (multi-mode flows) is found. The second bifurcation point (the bifurcation of three mode flow into four and five modes flows) is analyzed as well as the third one. The values of Reynolds number corresponding to the bifurcation points are calculated. The dependence of first bifurcation value vs. the halfexpansion angle is presented.
