| To solve the problems of thermal runaway and low conversion rate in the reactor of the novel low-temperature catalytic
inerting system, based on the FLUENT porous media model, the solid-phase energy equation was added by UDS, and the chemical reaction
was added by UDF, simulation models were developed for cylindrical, conical, and reverse conical reactor structures and their accuracy
verified using a self-built experimental platform. Two performance indicators, the conversion rate and oxygen consumption rate were
defined. The effects of the inlet gas temperature, inlet flow, and RP-3 fuel vapor concentration on the performance of the reactor were
studied, the operating range of the reactor was analyzed, and the performance differences of the three structures were compared in terms of
flow velocity. The results show that an increase in the temperature of the inlet gas and the volume concentration of RP-3 fuel, along with a
decrease in the inlet flow rate, can promote the occurrence of the reaction. The ignition temperature of the reactor is 470 K. Under identical
conditions, the conversion rates of the three types of reactors follow a descending order: conical, cylindrical, and anti-conical, with a differ?
ence in operating temperature range of 8-10 K. |
