Thermokinetic Oscillations in Acetaldehyde CSTR Combustion

Abstract

Acetaldehyde combustion process in CSTR has been simulated by means of a model capable of describing the complex dynamic behavior experimentally observed, including periodic cool flames, single and complex waveform periodic ignitions and jumps.

Critical discussion of models already existing in literature provided the basis for the development of work. Rigorous description of CSTR operation with all parametric dependencies has been implemented and a revised literature kinetic scheme has been adopted.

Thermokinetic switches operating in the system evolution are elucidated from the analysis of simulated non-isothermal events.
