Abstract:

This paper comprehensively reviews the current understanding of residence time distribution (RTD) within the plasticizing system of screw extruders. The core principles and characteristics of RTD were explained, and the primary influence factors were discussed. An overview of contemporary measurement techniques was also provided. The review highlighted the role of RTD as a robust indicator of mixing uniformity during extrusion and underscored its broad application potential in novel extrusion processes. Ultimately, investigating RTD offers innovative approaches for driving the extrusion industry toward greater precision and intelligent manufacturing.

Key words: residence time distribution, screw extruder, experimental measurement, numerical simulation
