COMPUTATIONAL ANALYSIS OF FLUID-STRUCTURE INTERACTION AND HEAT TRANSFER IN EXTRUSION PROCESSES

The extrusion process is integral to manufacturing, enabling the production of continuous profiles with precise cross-sections for various industries, including automotive, construction, and aerospace. This study focuses on the computational analysis of material flow and heat transfer during the extrusion of an L-type section under steady-state conditions. Finite element analysis is used to model the extrusion process.The research evaluates the impact of key parameters such as container temperature, ram velocity, and friction coefficients on the billets thermal profile and exit temperature. The study incorporates non-Newtonian flow dynamics, and thermal coupling to provide comprehensive insights into optimizing process efficiency, die design, and material flow uniformity. The results demonstrate the critical role of thermal and frictional parameters in enhancing extrusion quality and preventing material defects.
