Аннотация:The problem of stationary flow of viscous incompressible fluid in a plane confusor is investigated. Solution in the form of one-mode and multi-mode (containing sectors of flow and outflow) velocity profiles of the liquid, depending on the confusor angle, is obtained numerically. For this purpose, a high-precision numerical-analytical procedure based on the method of accelerated convergence (Newton's algorithm type) and continuation with respect to a parameter (Reynolds number) was developed. For multi-mode solutions, the existence of symmetric and asymmetric (with respect to the bisector of the confusor angle) modes is established. The evolution of velocity profiles as the Reynolds number increases is studied.
