Abstract
The thermal & hydraulic performances were examined experimentally for the stationary square channel with V shaped & 45°inclined arc of circle rib turbulators. Ribs were placed on opposite walls and the heat transfer coefficient and frictional factor were calculated. Stationary channel with aspect ratio one (W/H=1) was considered for the analysis. The thermal & hydraulic performances were measured by calculating the Nusselt number and frictional factor. Square ribs (w/e = 1) were considered as the baseline configuration. Rib geometries, comprising three rib height-to-channel hydraulic diameter ratio (blockage ratio) of 0.083,0.125 & 0.167 as well as rib spacing (pitch to height ratio) is 10. The heat transfer performance for the channel was calculated for Reynolds numbers 45000 to 75,000. The results obtained for the channel with different ribs configuration proved that the increase in rib width increase the thermal performance of the channels. By combined effect of rib width, rib spacing and flow parameters, the optimal cooling configuration was obtained.
