Abstract

A dynamic model for a bench-scale heat-flow calorimeter is derived in order to support the accurate reconstruction of the heat evolution in the reactor. The importance of describing the heat transfer between the reactor contents and the heating/cooling medium is described. The degree of discretization of the inner wall is deduced from the comparison of experimental and model-based frequency responses. The nonlinear behavior of the calorimeter is modelled and verified over a large range of operating conditions. Finally a qualitative assessment of the validity of such a dynamic model for both parameter and state estimation is provided.
