“…Numerous previous studies have investigated the parameters influencing rib performance. Ribbed channel flow is typically characterized by rib spacing, height, profile, angle of attack, and configuration [1][2][3][4][5]. In general, the ribs disrupt the flow boundary layer and promote flow mixing between the hot fluid near the wall and cooler main flow core.…”

“…Skullong and Promvonge [16] investigated the heat transfer and flow friction characteristics in a solar air heater channel fitted with delta-winglet type vortex generators. Sri Harsha et al [17] and Gupta et al [18] studied the local heat transfer distribution and pressure drop in a square channel and found that the 60° V-broken rib gives the heat transfer higher than the 90° continuous and profiled ones. Tanda [19] investigated the effect of transverse, angled ribs, discrete, angled discrete ribs, V-shaped, V-shaped broken and parallel broken ribs on heat transfer and flow friction.…”

“…The presence of ribs in a closed channel produces a complex flow field due to flow separation and reattachment between the ribs, which increases turbulence level and this leads to an increased heat transfer coefficient. Two vertical walls of the test section were made up of steel having 0.05 mm thickness [1]. Figure 1 shows formation of separation bubble and reattachment produced by ribs.…”
