Sažetak
The mathematical model of the dynamics of thermohydraulic processes in a high pressure tubular reactor for production of low-density polyethylen has been presented. The equations of the mathematical model have been formulated based on one-dimensional fluid flow assumptions. Polyethylen production has been modelled by multivaribale, nonlinear function defining dependence on temperature, concentration and flow velocity. Simulations results of typical operating conditions (start-up, regular operation, transient response to coolant temperature changes) provide a realistic description of the process.
