Abstract
A model to determine the residence time distribution (RTD) in a co-rotating twin screw extruder is proposed. The method couples a thermomechanical app roach with a chemical engineering approach and allows us to obtain the RTD without a fitting parameter. The global residence time is obtained using Lu dovic(R) twin screw modelling software and simple chemical reactors are cho sen to depict the screw profile. Experiments were carried out to validate t he model. The effects of feed rate and screw speed on the residence time di stribution were studied. Results are in good agreement with the predictions of the model.
