The present study focuses on an in-depth and meticulous exploration into the intricate realm of thermal management in three distinct yet widely utilized composite materials—namely, Liquid Crystal Polymer (LCP) Composites, Glass Fiber Reinforced Polymers (GFRPs), and Aramid Fiber Composites (Kevlar). This investigation employs an innovative counter-flow vortex tube system, meticulously analyzing and comparing the thermal efficiency of these materials under different intake configurations. Specifically, two distinct geometrical intake designs—a straight tube section and an advanced convergent tube section—are systematically scrutinized to unravel their impact on flow behavior and energy separation dynamics. A vast array of critical physical and flow parameters are methodically explored, including the influence of convergent angles (θ), intake pressures, cold mass fraction, and flow separation dynamics. Using the powerful ANSYS FLUENT simulation software, air is employed as the working fluid to simulate complex thermal interactions within the vortex tube system. Furthermore, an extensive analysis is performed on essential performance parameters, such as the hot temperature gradient (∆Th), cold temperature gradient (∆Tc), intake pressure variations, and overall thermal distribution to optimize the vortex tube’s cooling efficiency. The research findings of this investigation reveal that Aramid Fiber Composites (Kevlar) exhibit significantly superior thermal sustainability compared to Liquid Crystal Polymer (LCP) Composites and Glass Fiber Reinforced Polymers (GFRPs), particularly when subjected to a convergent vortex tube with an optimized 5-degree angle. This study not only enhances the fundamental understanding of composite material performance under permissible thermal limits but also paves the way for next-generation cooling strategies in aerospace, automotive, and high-performance engineering applications.
