摘　　要：本文分别从实验和理论角度研究了由水基磁性流体和煤油组成的不互溶物系中，单个分散相液滴在连续相中的流动及传热规律。通过对传热实验数据的整理，关联出一新的经验关系式，并将其与理论分析数值计算的结果进行了比较，两者的误差较小。本文还研究了磁场对流动和传热的影响，随着场强的增加，液滴下落的均速度增加，传热系数提高。In this paper,a study is carried out both experimentally and theoretically on how an in-dividual drop of dispersed phase flows and transfers heat in continuous phase,two immisci-ble substances composed of water-based ferrofluid and kerosene. A new empirical heattransfer relation is then obtained by correlating with the experimental data,and the compari-son is made with the numerical value,The error turns out to be small.In addition.the efectof magnetic field on the flow and heat transfer is also looked into.
