“…4b). The numerical approach based on the 1D modelling of the nitrogen cooling was tested and validated in different previous works of the authors [8][9][10][11], proving the good accuracy of the achieved results at very reduced computational time if compared to the approach based on a full 3D model of the nitrogen flow. In this work, the accuracy of the numerical model was demonstrated by analyzing, in terms of temperature prediction, the experimental-numerical differences in both uncooled and cooled conditions.…”

“…In addition, the level of complexity force not only through numerical approaches, but also demands for automated, robust and comprehensive methodologies. If many works have been reported on aluminum extrusion FE (Finite Element) modelling [6,7], stating the robustness and reliability of the approach, only recently Reggiani and Donati [8], and Pelaccia et al [9,10] proposed a comprehensive numerical model for the prediction of the thermal gradient during the extrusion process with nitrogen cooling. In addition, very promising results have already been achieved, by the same authors, by integrating the comprehensive FE model in an optimization platform able to change the channel sections iteratively and automatically along the path [11].…”

“…The authors of the paper have still proposed a numerical model for the thermal field prediction during the extrusion process, modelled as 3D, with nitrogen flowing in a simplified 1D channel [9][10][11]. These works provided the basis for the present paper, in which the FE model of the cooled extrusion process was integrated within the optimization platform, modeFRONTIER®, with the aim to automatically detect the optimal channel design.…”

“…The capability of nitrogen cooling within a conformal channel was experimentally and numerically assessed, for the extrusion of AA6063 aluminium and ZM21 magnesium alloys. 28 A platform for testing the liquid nitrogen cooling for multi-die design was proposed. 29 To provide extruders and die manufacturers with a numerical tool particularly for the thermal distributions of dies, a FEM model for the extrusion process with the liquid nitrogen cooling system was developed.…”

“…presented a finite element method (FEM) to cool down channels, which is mainly for die plastic injection molding and casting applications. The capability of nitrogen cooling within a conformal channel was experimentally and numerically assessed, for the extrusion of AA6063 aluminium and ZM21 magnesium alloys 28 . A platform for testing the liquid nitrogen cooling for multi‐die design was proposed 29 .…”
