Mathematical Modelling and Identification of the Flow Dynamics in Molten Glass Furnaces

In the paper a new method for computer aided modelling and identification of flow dynamics in molten glass is presented and numerically analysed. The process of the construction of the model occurs in several steps on which the sub-models with differentiated mathematical descriptions (with distributed or lumped differential equations) and dynamical features (with inertial and oscillatory characteristics and with slow and fast changeable dynamics) are setting up. This method makes possible to prepare the models of glass tank furnaces of high degree of accuracy, described with the equations of high orders. The models are suited well to estimate technological parameters of glass tank furnaces and to control the glass melting process.
