Thermo-hydraulic Performance of Annular-Finned Double-Pipe Heat Exchanger: Numerical and Experimental Investigation of Metallic and Polymer Composite Tube Wall Materials
Abstract: Double-pipe heat exchangers are central to the process industries — dependable, easily maintained, and straightforward to fabricate. Their conventional form relies on metallic tube materials, most often copper or stainless steel. Both metals conduct heat well, but they are dense, prone to corrosion in aggressive service environments, and increasingly at odds with the light-weighting goals that drive modern system design. Fibre-reinforced polymer composites, epoxy-based materials, and thermally enhanced thermoplastics such …

Thermo-Hydraulic Enhancement of Annular Finned Shell-and-Tube Heat Exchangers Using Epoxy-Based Polymer Composites: A Material–Geometry Coupled CFD Investigation
Abstract: Shell-and-tube heat exchangers remain a backbone of industrial thermal systems, yet their performance is often limited by relatively low shell-side heat transfer and the weight and cost associated with conventional metallic components. In this context, the integration of polymer composite materials offers a promising pathway toward lightweight, corrosion-resistant, and performance-tunable heat exchanger designs. The present study investigates the thermo-hydraulic performance of a straight-tube shell-and-tube heat exchanger equipped with annular fins, …

Thermo-Fluid Characterization of Corrugated U-Tube Shell-and-Tube Heat Exchanger with Polymer Composite Tube Wall: A Combined CFD and Experimental Investigation
Abstract: Shell-and-tube heat exchangers built with metallic tubes work well thermally, but corrosion problems, extra weight, and the inability to adjust the wall’s thermal properties through material choice remain genuine engineering headaches, particularly for corrosive or weight-critical applications. Over the past few years there has been a fair amount of interest in replacing metal tubes with polymer composite alternatives, since blending thermally conductive fillers — graphite nanoplatelets, boron nitride platelets and …
