چکیده
In this numerical work, heat transfer characteristics of humid air in a rectangular channel as solar heater equipped with V-shaped ribs has been investigated. The impacts geometrical parameters proposed such height, pitch, and angle relative to flow direction, well humidity Reynolds number inlet on thermal performance have evaluated. results achieved using commercial Computational Fluid Dynamics (CFD) code, ANSYS FLUENT 18.2, which works based finite volume method. Outcomes shows that, over wide range operating conditions, utilizing cause boundary layer separate reattach, eventually enhance rate. Increasing the rib produces stronger secondary flows, leading higher local velocities greater Moreover, increasing from 0% 50% leads improve by up 6%. As increases 4000 12,000, average Nusselt rises 7.3% 31.4% for pitches 6 16 mm, respectively. demonstrate how can be improved ribs.
