dc.description.abstract | This study investigates and compares the computational fluid dynamics (CFD)
analysis of smooth absorber finned tubes and helical fin absorber tubes used
in solar water heating collectors. The three-dimensional numerical simulations
were conducted using COMSOL Multiphysics software to analyze fluid flow
and heat transfer characteristics. The research is structured into three main sections. In the first section, absorber finned tubes made from different materials,
including stainless steel, iron, copper, and aluminum, are evaluated to determine their impact on thermal performance. The second section focuses on
the comparative analysis of two different geometric configurations of absorber
finned tubes, assessing their influence on heat transfer efficiency. The final
section investigates the performance of a selected absorber tube—identified as
optimal from the previous analysis—by introducing internal helical fins with
varying pitch sizes of 25 mm, 50 mm, 75 mm, and 100 mm. The influence of
these internal fins on heat transfer enhancement and flow characteristics is
systematically examined. The findings of this study provide valuable insights
into the optimization of absorber tube designs for solar water heating systems,
contributing to improving efficiency and performance in thermal energy applications | en_US |
