文摘:实验研究水蒸汽凝华结霜过程中在冷壁面上形成的霜层的导热系数，并以此验证作者曾提出的霜层导热系数的理论结果 - Abstract : the paper presents a theoretical study on the thermal conductivity of frost formation on cooled flat plate under forced convection . taking the porous meditum as a physical model of frost layer , according to the theories of heat and mass transfer , the formula on heat conductivty of frost formation is derived
文摘:研究水蒸汽凝华结霜过程在冷壁上形成的霜层的导热系数，依据随机管子多孔介质霜层模型，假设霜层是由孔隙空间与冰晶骨架构成的多孔介质，其中孔隙空间由随机毛细管及连接管子的接头形成，湿空气中的水蒸汽在霜层的孔隙空间中扩散输运并凝华结霜，根据传热传质学理论，导出霜层导热系数关系式。
