Abstract EN
An experimental investigation was carried out to study the effect of Large Eddy Breakup Devices with of circular ribs on one heated wall of a rectangular duct with fully developed turbulent flow , on heat transfer and flow characteristic.
The artificially roughened duct has an aspect ratio (W/H) of 10, hydraulic diameter of 72.72 mm, relative roughness pitch (P/e) of 10 and relative roughness height (e/Dh) of 0.05.
The experiments were conducted by varying airflow rate in terms of Reynolds number ranging from 3.2x104 to 6.2x104 and constant heat flux of 600 W/m2.The heat transfer and friction characteristics of the duct were compared with those of a smooth duct under similar experimental conditions.
It was found that there was a significant enhancement of Nusselt number for combined high Reynolds number (2.6) and friction factor (3.47).
