| Abstract: | Based on the consideration of the effect of fouling on heat transfer performance of heat exchanger,the concepts of equivalent entire fouling heat resistance R fe and fouling function of heat exchanger are presented and the monitoring method of R fe is given,the effects of flow pattern,heat transfer effectiveness and heat capacity rate ratio of cold and hot fluids on the equivalent entire fouling heat resistance are discussed.: Based on the consideration of the effect of fouling on heat transfer performance of heat exchanger,the concepts of equivalent entire fouling heat resistance R fe and fouling function of heat exchanger are presented and the monitoring method of R fe is given,the effects of flow pattern,heat transfer effectiveness and heat capacity rate ratio of cold and hot fluids on the equivalent entire fouling heat resistance are discussed. |
