Heat Transfer in Crossflow Over Cylinders Between Two Parallel Plates

Abstract

The heat transfer coefficient and pressure drop are measured for laminar and turbulent incompressible flow over an in-line cylinder array (eight copper tubes) between two parallel plates. Data are given using two different aspect ratios for the intermediate range of the Reynolds number between 220 to 2800. A criterion is defined for flow transition from laminar to turbulent. The pressure and heat transfer data are compared to numerically computed data obtained for laminar flow and the results exhibit reasonably good agreement.
