摘　　要：利用从传热传质角度结合表面化学反应知识模拟CaCO_3污垢形成过程的数学模型,对缩放管不同工况进行了数值模拟计算。得出不同工况下,缩放管内CaCO_3污垢的沉积率、剥蚀率、污垢热阻随时间的变化规律以及它们与流速、工质浓度、温差的关系。In this paper the CaCO3 fouling process in convergent-divergent tube was calculated under different conditions with the surface chemical reaction and heat and mass transfer.Then we got the laws of the deposition rate,the erosion rate,the fouling resistance of CaCO3 fouling as the time changing in convergent-divergent tube under different conditions.
