| Details | Numerical investigations on the heat transfer and pressure loss of a plate-fin heat exchanger with V-shaped oblique wavy surface have been conducted. The effects of pointing direction of V shape, oblique angle and wave amplitude are systematically studied to find out the geometry with the best thermal-hydraulic performance. It is found that the oblique wavy surface induces two pairs of counter rotating secondary flows which significantly enhance heat transfer irrespective of the pointing direction of the V shape. Meanwhile, the oblique wavy surface with the V shape pointing downstream shows relatively low pressure loss. |
