Combustion of PMMA (Polymethylmethacrylate), PE (Polyethylene) and PS (Polystyrene) in a Ramjet

摘要

The combustion behavior of polymethylmethacrylate (PMMA), polyethylene (PE) and polystyrene (PS) was investigated in a connected pipe test facility. Instantaneous and local regression rates were determined. Spectroscopy was applied. Main issues of the present investigation are the establishing and understanding of the most important phenomena that control or emanate from the combustion of a cylindrical solid fuel with a rearward facing step. Main utilization is for solid fuel ramjets, safe burning of toxic waste and hot gas generators. During the investigation attention was focussed on regression rate, efficiency, temperatures, and soot production.
