摘要:
A numerical model is developed to determine convective heat transfer distributions for an array of submerged planar jets impinging on a uniform heat flux or constant temperature moving surface where the surface motion is directed perpendicular to the jet planes. Unlike prior related work, the model accounts for the interaction between neighboring jets in the array without imposition of an imposed cross flow. The effects of surface speed, nozzle separation distance within an array, nozzle height, and Reynolds number on the flow field, coefficient of friction, and Nusselt number are investigated. Results suggest that neglecting surface motion effects can lead to overestimates of heat transfer.
