A Jet Stirred Reactor for Combustion Studies: Design and Characterization

Abstract

A Jet Stirred Reactor for Combustion Studies: Design and Characterization Abstract–A stainless steel jet stirred reactor (JSFR) has been designed and constructed, capable of operating under pressures up to 20 atm and temperatures up to 1000 K and residence times as short as 0.015 s. Complete mixedness has been experimentally checked by means of mass-spectrometric analysis of argon pulses in a nitrogen steady flow. A Nusselt type correlation has been developed to evaluate the heat transfer coefficient for this kind of reactors. JSF reactor technique has been applied to study the dynamic behaviour of air-stoichiometric mixtures of n.heptane and i.octane. Runs have been performed both at constant and variable operation pressure. Heat release rates (HRR) of combustion processes have also been systematically evaluated.
