摘　　要：通过静态和动态两种方法,进行了高压静电抗垢强化传热实验研究.静态实验结果表明,高压静电场能够使污垢晶体形态发生改变,由六面体结构变为树枝状和薄片状结构,并促进污垢晶体尺寸的增大。动态实验结果表明,成垢溶液经过高压静电处理以后,污垢热阻明显减小,流速的增大能够增强抗垢能力。In this paper, anti-fouling experiments for heat transfer enhancement using high-voltage electrostatic field are carried out by static and dynamic methods. The results of static experiment indicate that, under the high-voltage electrostatic field, crystal changes in configuration from hexahedron to branch or slice, and enlarges in size. Furthermore, the results of dynamic experiment indicate that, the fouling resistance decrease extraordinarily with treatment of high-voltage electrostatic field, and anti-fouling capability of solution increases with high flow velocity.
