In the present study, a numerical study is performed to one plain and six circular tubes with discrete ribs in two arrangements; in-line and staggered. Air is used as a working fluid at3,600 Re 16,525. The number of ribs is changed from 4 to 12 to study its effect on heat transfer rate (HTR) and pressure drop (ΔP). PEC is performed to estimate the thermal hydraulic efficiency (THE) for the all test tubes. The flow phenomena and temperature contours are shown to illustrate the temperature distribution and vortices.
