when the temperature was low, the composite fouling resistance was greater than both particulate and crystallization fouling; the crystallization fouling resistance was the smallest.
当水温较低时,混合垢的渐近污垢热阻明显大于颗粒垢和析晶垢,析晶污垢热阻最小;
as the temperature increased, the fouling rate increased notably, the fouling resistantance increased and approached the asymptotic fouling resistance rapidly.
随温度的升高,结垢速率显着加快并迅速达到污垢稳定状态期,渐进污垢热阻也增大;
the variation of fouling resistance and frictional resistance coefficient of heat exchanger using connate yangtze river water as cooling water is tested experimentally.
通过实验方法测试了以原生长江水为冷却水的换热器污垢热阻和摩阻系数的变化。
however, the deepening of groove brought on the increase of fouling rate and the decrease of fouling induction period, meanwhile the fouling resistance tended to decrease.
而槽深增大,使结垢速率增大和诱导期减小的同时,污垢热阻变化趋于减小。
furthermore, the results of dynamic experiment indicate that, the fouling resistance decrease extraordinarily with treatment of high-voltage electrostatic field, and anti-fouling .
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。
as the temperature rose, the induction period tended to disappear and the fouling resistance would relevantly increase.
随着流速的增大,诱导期随之延长,同时结垢速率减小,渐进污垢热阻减小。
