The prime novelty of the present research is the numerical finite-difference solution of Navier-Stokes equations in the curl transfer form for the viscous workpiece flow through 2θ acute-angled angular dies of Segal geometry during Equal Channel Angular Pressing, taking into account the classical rectangular (2θ0=90º) and novel modified 2θ0-inclined or 2θ0-beveled punch shapes with 2θ0=2θ.
