| چکیده | ||
| This article presents a numerical analysis of the turbulent air flow in the rectangular channels equipped with ribs. The ANSYS FLUENT 17 software is used to solve the mass and momentum equations employing the finite volume approach. To get the best overall performance and to measure the pressure drop, the ribs are positioned in three different lengths. Additionally, tests and comparisons are conducted on the temperature rise of the channel wall for six alternative configurations of the ribs. The used rib lengths are 150 mm, 60 mm, and 30 mm. Experiments are conducted at the Reynolds numbers ranged from 10,000 to 35,000, pitch to rib height proportional (p/e) of 5.0, and rib height to channel height proportional (e/H) of 0.333. The results of ribs placed continuous on the upper surface of the channel and intermittent ribs placed on the lower surface of the channel in a staggered arrangement (TCBISR) case demonstrated a clear superiority when compared to the other cases evaluated, yielding the highest overall performance. Despite this instance's outstanding performance, the TCBISR case yields the highest values of friction factor. | ||
