【摘要】 利用萘升华传质/传热比拟实验方法,研究了每管六涡扁长椭圆翅片管换热器换热板芯在三角翼形涡产生器不同翼高时的换热和阻力特性,分析了涡产生器翼高的变化对错排椭圆翅片管换热器传热与阻力特性的影响,为该型换热器设计提供了一定的理论依据。更多还原

【Abstract】 The paper investigates the factor of winglet height on heat transfer enhancement performance of test core of finned oblate oval tube heat exchangers with six wing-type vortex generators per tube via mass/heat transfer analogy of naphthalene sublimation. As a referencable theoretical foundation in following design work, the present study evaluates the effect of change of winglet height on heat transfer and pressure drop characteristics of such type heat exchangers.更多还原
