Abstract The hydrothermal behavior of air inside a solar channel heat exchanger equipped with various shaped ribs is
analyzed numerically. The bottom wall of the exchanger is kept adiabatic, while a constant value of the temperature
is set at the upper wall. The duct is equipped with a flat rectangular fin on the upper wall and an upstream
V-shaped baffle on the lower wall. Furthermore, five hot wall-attached rib shapes are considered: trapezoidal,
square, triangular pointing upstream (type I), triangular pointing downstream (type II), and equilateral-triangular
(type III) cross sections. Effects of the flow rates are also inspected for various Reynolds… More >
