... (5–20 mm) is also investigated in these three models. On the better model 3, rectangular ribs are deployed on few or all absorber plates, consequently, five channels, i.e., models 4–8 are generated. In these models, the rib parameters are adjusted, and advance inquiries are accomplished. 3D...

... transfer and on the thermo-hydraulic parameter. A wide range of inlet Reynolds number (Re), 100 ≤ Re ≤ 10 5 , inlet swirl ratio (S), 0 ≤ S ≤ 20, and the gap spacing ratio (G), 0.01 ≤ G ≤ 0.1 is considered in the study. The rectangular grooves are characterized by ribs with three dimensionless lengths...
