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 …

Evaporative Cooling By Using Different Porous Materials
Abstract: The method of evaporative cooling involves raising the air temperature by causing water vapour in an airstream to evaporate. Waterneeds the latent heat of vaporisation to evaporate, and this heat is produced by ambient air and a drop in air temperature. A porousmedium is necessary for both direct and indirect evaporative cooling in order to allow heat and mass transfer between the medium'swater and the air moving through it, or …

Ilaj bil-Ma’ (Hydrotherapy) as a Regimenal Modality in Pain Management: Conceptual Foundations in Unani Medicine and Modern Correlation
Abstract: Waja‘ (pain) is one of the most common clinical complaints encountered worldwide and remains a leading cause of disability, impaired functional capacity, and diminished quality of life. In the Unani system of medicine, pain is not considered merely a symptom but a significant manifestation of disturbed physiological balance. Classical Unani scholars describe pain as arising from derangement in Mizāj (temperament), imbalance of Akhlāṭ (humours), Sudad (obstruction within bodily channels), Waram …
