CFD SIMULATION OF ECAE THROUGH A MULTIPLE-ANGLE DIE WITH A MOVABLE INLET WALL

摘要: The present work is focused on a 2D fluid dynamics description of equal channel multiple angular extrusion (ECMAE) or pressing (ECMAP), using numerical mathematical simulation for viscous flows physical polymeric materials models through die with movable inlet wall. A finite-difference model plane Newtonian flow an incompressible continuous medium in multiple-angle region wall, based the formulation and solution boundary value problem Navier-Stokes equations curl transfer form, derived. estimation influence direction movement entrance wall computational lines, stream functions, velocity fields was carried out within scope developed die. proposed hydrodynamic approach extends ideas concerning macroscopic rotation formation withi...
