管排数对涡产生器式圆管板式翅片传热的影响
Heat Transfer Enhancement and Pressure Loss of Fin-Tube Heat Exchangers with Wing-Type Vortex Generators Results from the Variation of Tube Rows
【摘要】 利用萘升华传质/传热比拟实验原理,研究了翼形涡产生器对叉排圆管板式翅片换热和阻力特性的影响,分析了涡产生器式叉排圆管板式翅片管换热器在不同管排数下的传热与阻力特性.并对换热器板芯结构做了综合评价.
【Abstract】 An experimental study using naphthalene sublimation has been carried out to investigate the heat transfer and pressure drop characteristics of circular fin-tube heat exchangers with the staggered arrangement for the WVG’s existence. The simulative study quantitatively analyzes the heat transfer performance on the condition of the variation of Re number and tube rows. The performance evaluation and correlative conclusions would be useful for the design of heat exchangers.
