Fouling Detection in Heat Exchangers

By Sabrina Delrot, Krishna Busawon, Mohamed Djemaï, François Delmotte and Michel Dambrine


This paper deals with the design of a nonlinear observer for the purpose of detecting the fouling phenomenon that commonly occurs in heat exchangers. First, the general model of the heat exchanger is presented in terms of partial differential equations. Next, a simplified lump model is derived that is suitable for the observer design. The observer gains are generated by using appropriate Lyapunov functions, equations and inequalities
