| Аннотація | Context. The nonlinear stationary problem of flow past a body of revolution by a viscous incompressible fluid is examined in this article.
Objective. The purpose of this work is to develop a new method of numerical analysis of stationary problems of flow around bodies of revolution by viscous incompressible fluid.
Method. The mathematical model of the process under consideration is a nonlinear boundary value problem for the stream function obtained by the transition from the system of Navier-Stokes equations to one nonlinear equation of the fourth order. A special feature of the formulation the task of the flow past body is that the boundary value problem is considered in an infinite region and both boundary conditions on the boundary of the streamlined body and the condition at infinity are imposed for the stream function. Using the structural method (the R-functions method), the task solution structure, that exactly satisfies all the boundary conditions of the task, and also guarantees the necess |
