Thermal Engineering: Principles, Evolution, and Comparative Analysis with Classical Approaches
Abstract: Thermal engineering is the study of heat transfer, thermodynamics and energy conversion systems. However, through the years it has progressed from classical theories, which relied on empirical correlations, to enhanced computed and nanotechnology based approaches. This paper highlights the principles of thermal engineering, its important systems and latest developments of thermal engineering and provides extensive comparisons between the classical (traditional) methods and the most recent developments or innovations such as …

Thermal Performance Enhancement Strategies for a Compact Solar PV-Powered Concentrating Water Heating System Through Integrated Collector Design
Abstract: Solar water heating systems have emerged as one of the most promising renewable energy technologies for reducing dependence on conventional fossil fuels and electricity-based water heating. However, the thermal performance of compact solar water heaters is often limited by inadequate solar absorption, poor heat transfer, and thermal losses within the collector assembly. This study presents a theoretical investigation of thermal performance enhancement strategies incorporated into a compact solar photovoltaic (PV)-powered …

Thermo-Hydraulic Performance of a Double-Pipe Double-Pass Heat Exchanger using Annular Fins and Graphite-filled Epoxy Composite Tubes
Abstract: Double-pipe heat exchangers remain one of the most widely adopted thermal devices because of their simple construction, operational reliability, and ease of maintenance. Nevertheless, their performance is often constrained by the limited heat transfer area of smooth tubes and the long-term challenges associated with metallic materials, including corrosion, scaling, and structural weight. Recent advances in thermally conductive polymer composites provide an opportunity to overcome these limitations by replacing conventional metals …
