Abstract
Tube enhanced with tape with three parts was employed in this suggested solar system to absorb the highest radiation. The three parts are connected together with various angle (beta). Carrier base fluid has been mixed with CuO nano-powder and homogeneous model was utilized for properties. For better capturing the behavior of flow near the wall, multilayers were utilized to control the range of Y+. Components of irreversibility in form of bar charts and contours for velocity and exergy drop have been illustrated in the results. Inlet velocity and angle of tape (beta) were assumed as active factors. Validation test based on numerical data shows a good accommodation. As the angle elevates, the nanofluid rotational speed increases and more collision with wall happens which decrease the wall temperature around 0.0257%. Xd reduces about 5.19% and 5.87% with rise of beta from 0 to 45 degrees and 90(o). Frictional entropy augments about 9.88% with a rise of beta. As Re augments, the outer wall becomes cooler at 0.87% and Xd declines by 92.31% when beta = 45 degrees.
