“…Other studies utilizing water fluid have reported lower efficiency and higher output temperatures. To tackle this challenge, a novel FPC was devised, featuring a double-ducted cellular polygal cover, which demonstrated increased efficiency, although it resulted in a persistently high-water consumption rate [10].…”

In this work, CFD analysis of smooth absorber fin tube and screw absorber fin tube used in solar water heater collector is considered and compared. Three-dimensional numerical CFD model simulations were performed using flow simulation in COMSOL Multiphysics software. A flat absorber wing tube made of different materials (Stainless steel, Iron, Copper, Aluminum) is evaluated. At the same time, different water inlet velocities were tested. Various velocities such as 0.01 m/s, 0.02 m/s, 0.025 m/s, 0.035 m/s have been simulated and here the inlet velocity of 0.2 m/s is close to optimal for the given size, the outlet velocity at this velocity is suitable for direct consumption.
