A stochastic approach to the analysis of chemically reacting systems-VII. Influence of external noise on the behaviour of a fluid bed with nonlinear reaction rates

Abstract

The basic model of Ligon and Amundson (1981, Chem. Engng Sci.36, 653-660) has been employed to assess the influence of white and nonwhite external noise on the behaviour of a fluidized bed where nonlinear reaction occurs. The paper presents a self-consistent linearization scheme for such problems and illustrates its use by considering an example. The analysis gives a quick and easy solution for such complex cases. The analysis for other examples indicates that white and coloured (or nonwhite) noise have different effects on the reactor's behaviour and also reveals that the presence of noise destroys features such as multistationary behaviour which exists in the absence of noise.
