Experimental investigation of the effects of simultaneously using plate fins and a helical screw rod with a core rod on a double-tube heat exchanger’s thermal performance | Journal of Thermal Analysis and Calorimetry

The article titled "Experimental investigation of the effects of simultaneously using plate fins and a helical screw rod with a core rod on a double-tube heat exchanger’s thermal performance" explores innovative methods to enhance the efficiency of double-tube heat exchangers (DTHX). The study examines the combined use of helical screw rods with core rods (HSR-CR) and plate fins (PF) to improve thermal performance. It provides detailed experimental data on parameters such as the Nusselt number, friction factor, and overall heat transfer coefficient, demonstrating significant improvements compared to traditional smooth DTHX designs. The research highlights the importance of passive heat transfer techniques and their applications in industries like power plants, air conditioning, and waste heat recovery.

This resource is particularly valuable for engineering students and professionals as it offers insights into cutting-edge methods for optimizing heat exchanger performance. It emphasizes the practical applications of thermodynamics and fluid mechanics, making it a useful reference for those interested in energy efficiency and sustainable engineering solutions.
