Numerical Investigation of Heat Transfer Characteristics Using Different Discrete Rib Arrangements

Numerical study was carried out to study effect of different discrete rib arrangements on heat transfer performance. These rib arrangements include variously angled ribs, different. Spacing and also different angle combinations. Standard k-ε model is used for turbulence modelling. This study is carried out at Reynolds no. 22384 which was selected from previous studies. Different rib arrangements like inline and staggered for 30?, 45 and 60, discrete V's arrangement with different spacing, diamond like discrete rib arrangement with half and complete obstruction, inline and staggered connected V's and angle combination rib arrangements are studied numerically in this study. It is observed that 45 inline V-shape rib arrangement shows better Thermal Enhancement Factor (TEF) as compared to other arrangements and value of TEF is observed to be 1.0011. Ribs arranged in discrete V's shape with different spacing shows comparatively less heat transfer enhancement. Citation: Sandip T. Jadhav, PES's Modern College of Engineering, Pune; R. D.
