Numerical study of two-dimensional separation on the basis of the Navier-Stokes equations

Numerical study of two-dimensional separation on the basis of the Navier-Stokes equations The phenomenon of the separation of a flow from the surface of a body, and the transfer of fluid which is slowed down in the boundary layer to the exterior flow, is of primary importance both in practice and in theory. From the practical point of view, flows with separation are important primarily because the separation of the boundary layer usually sets the upper limit of the efficiency, and therefore of the application, of many aerodynamic devices. From the theoretical point of view, the greatest importance lies in the problem of selecting the unique solution and the problem of elaborating effective numerical methods of studying flows with separation. The complexity of experimental research and the variety of problems connected with flow past bodies where separation occurs make the theoretical study of their general laws important. The aim of this work is to study separation zones and certain processes of controlling them on the basis of the full Navier—Stokes equations in the case of two-dimensional steady flows of a viscous incompressible fluid for moderately low Reynolds numbers. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fluid Dynamics Springer Journals

Abstract

The phenomenon of the separation of a flow from the surface of a body, and the transfer of fluid which is slowed down in the boundary layer to the exterior flow, is of primary importance both in practice and in theory. From the practical point of view, flows with separation are important primarily because the separation of the boundary layer usually sets the upper limit of the efficiency, and therefore of the application, of many aerodynamic devices. From the theoretical point of view, the greatest importance lies in the problem of selecting the unique solution and the problem of elaborating effective numerical methods of studying flows with separation. The complexity of experimental research and the variety of problems connected with flow past bodies where separation occurs make the theoretical study of their general laws important. The aim of this work is to study separation zones and certain processes of controlling them on the basis of the full Navier—Stokes equations in the case of two-dimensional steady flows of a viscous incompressible fluid for moderately low Reynolds numbers.
