Numerical heat transfer Prediction for laminar flow in a circular pipe with a 90 bend
Laminar air flow in a 90° bend has been studied numerically to investigate convective heat
transfer, which is of practical relevance to electronic systems and refrigeration piping layout.
CFD simulations are performed for Reynolds number in the range 200 to 1000 at different

Abstract
Laminar air flow in a 90° bend has been studied numerically to investigate convective heat transfer, which is of practical relevance to electronic systems and refrigeration piping layout. CFD simulations are performed for Reynolds number in the range 200 to 1000 at different bend radius ratios (5, 10 and 20). The heat transfer characteristics are found to be enhanced in the curved pipe compared to a straight pipe, which are subjected to the same flow rate. The curvature and buoyancy effectively increase heat transfer in viscous laminar flows. The correlation between the flow structure and the heat transfer is found to be strong.
