Influence of Scaling on the Performance of Shell-and-Tube Heat Exchangers

Fouling in shell-and-tube heat exchangers was modeled by combining Hasson's ionic diffusion model for scaling from CaCO 3 solutions with a model for predicting the temperature distribution developed by Gaddis and Schlünder. Using the computed results, clean heat exchanger design rules were test...

Zusammenfassung:	Fouling in shell-and-tube heat exchangers was modeled by combining Hasson's ionic diffusion model for scaling from CaCO 3 solutions with a model for predicting the temperature distribution developed by Gaddis and Schlünder. Using the computed results, clean heat exchanger design rules were tested for fouling conditions. The effects of fouling on the efficiency of heat exchanger configurations were determined.
