Abstract
<jats:p>This volume explores theoretical and applied developments in thermodynamics and energy system behavior across engineering environments. It emphasizes heat transfer mechanisms, energy conversion cycles, entropy analysis, thermo-chemical systems, and thermal efficiency enhancement strategies. Research examining renewable thermal systems, waste-heat recovery, heat exchanger optimization, thermal storage materials, and energy system sustainability assessments is encouraged. Contributions integrating experimental investigation, computational fluid dynamics (CFD), thermodynamic modeling, and performance diagnostics are highly relevant. The objective is to support high-efficiency, low-loss, and environmentally responsible thermal system design for industry and infrastructure.</jats:p>
