Abstract

In order to study the pressure peak caused by deflagration in starting process of gas jet heater, a simulation method was carried out. The deflagration simulation was divided into cold-test and hot-test processes. The mass conservation equation, energy conservation equation and oxygen/oil combustion reaction equation were used to analyze the pressure of combustion chamber in both cold-test and hot-test. The analysis results suit well with the prototype test which shows the applicability of the method. Based on this method, peak pressure of the deflagration under a given condition was calculated. The peak pressure calculated (13.5MPa) exceeded the design pressure (5Mpa), which led to the damage of the gas jet heater.
