纺织品热湿传递中的交叉效应

摘要

The Soret effect and the Dufour effect on process of thermal and water vapoure transfer are discussed in this paper.The cross action between water vapoure flow in air and heat energy flow is remarkable difference with blend gas of mix limitness of contents.In test result,the thermal conductive coefficient stem from mass flow KC will greater than forecast value from calculation with known theory over 1 to 3 orders.And the mass diffusing coefficient stem from heat flow DT also greater than forecast value from calculation with known theory over 1 to 3 ordesrs.%讨论了在热湿同时传过程中Soret效应和Dufour效应的影响程度.实验证明,湿空气中热湿交叉效应的影响程度远远大于其它可无限溶混的非极性混合气体.实测所得的质导热系数KC测和热导质系数DT测要比原理论推算值大1～3个数量级.
