Simulation of a Stationary Turbulent Flow of a Cylindrical Obstacle by Viscous Incompressible Fluid in a Stepped Tube

A. S. Kravchuk, I. A. Tarasyuk

Abstract


A technique for the analysis of stationary turbulent flows of an incompressible fluid is developed using the FLOTRAN CFD module of the ANSYS 10 ED program. It is established that the nature of the flow and the formation of vortices are influenced by the geometry of the region in which the is studied and also by the presence of obstacles, their shape and geometric location. The technique can be applied practically in all branches of mechanical engineering connected with the calculation of the motion of an incompressible viscous fluid in geometrically complex structures, mechanisms and pipelines.
