Hydrodynamical simulation of equal channel multiple angular extrusion through the U-shaped tapered die

Abstract


The present article is focused on the study of local flow dynamics and the character of formation of rotary modes of deformation during Equal Channel Multiple Angular Extrusion of workpiece through the U-shaped tapered die. The present local flow problem through the U-shaped tapered die was analyzed with an introduction of physical simulation methods and numerical fluid dynamics simulation techniques. The computational approach has been grounded on the basis of the numerical finite difference solution of boundary value problem for Navier-Stokes equations in the curl transfer form for the local viscous flow of incompressible Newtonian continuum through the U-shaped tapered die. Derived research results allow us to draw a conclusion that the design geometrical implementation of parallel slants within 2-turn U-shaped tapered die provides the localization of maximal tangential stresses within workpiece volume just in the vicinity of these parallel slants during Equal Channel Multiple Angular Extrusion of workpiece through the U-shaped tapered die.
