Analyse numérique tridimensionnelle du comportement thermique d'un échangeur de chaleur à tube spiralé équipé de chicanes

Abstract

Heat exchangers are essential engineering devices widely used across various industrial sectors to facilitate heat transfer between two fluids In this study, a shell-and-tube heat exchanger is taken as the reference model. A numerical investigation was carried out using ANSYS Fluent software on two spiral tube heat exchanger configurations with identical outer dimensions. The first configuration features a simple spiral tube design, while the second includes five baffles, added to enhance heat transfer performance. The study focuses on the variation of outlet temperature with respect to fluid velocity, with a comparative analysis between the two models.
