USE OF RTD AND LOCAL TRANSFER REPRESENTATION TO OBTAIN A TRANSIENT MODELLING OF A LIQUID-SOLID SYSTEM

Abstract

The input-output thermal transient modelling of a multistage liquid-solid fluidized bed is proposed. This model is based on a flow modelling obtained from RTD measurements and a local heat transfer model. Experimental data are well represented by the model. Furthermore, sensitivity problems are studied and literature values of heat transfer coefficients are discussed.
