چکیده
Abstract This paper deals with the reconstruction of the inlet temperature profile of a melted polyethylene (PE) flowing through an extrusion die. The inverse heat transfer problem is formulated as an optimisation problem by considering both the energy and the Navier-Stokes equations. It is solved by using the conjugate gradient algorithm. Experimental results are presented and show the effect of the pressure drop combined with the viscous dissipation effect on the temperature profile along the channel die.

We deal with the problem of recovering a memory kernel k(t, η), depending on time t and on a spatial variable η, in a parabolic integro-differential equation related to a bounded domain Ω ⊂ R. We show that, under suitable assumptions and two pieces of additional information, our identification problem can be uniquely solved locally in time.

In this paper, an effective nonstationary boundary estimation scheme in EIT is presented based on the interacting multiple model (IMM) algorithm. The inverse problem is treated as a stochastic nonlinear state estimation problem with the time-varying boundary (state) being estimated on-line with the aid of the IMM algorithm. In the design of the IMM algorithm multiple models with different proce...

متن کاملEffect of Die Profile on Mechanical Properties of Product in Extrusion of Rods
In any metal forming process, both the strain rate and deformation rate depend on the die profile. The die profile also, is responsible for the non-uniformity of the deformation along the cross-section. These affect the quality and mechanical properties of the product. Therefore, if a die is designed, in which the affecting variables can be controlled spontaneously it is hoped to obtain a produ...
