The combustion chamber with an evaporative stabilizer improves the spray distribution downstream of the stabilizer by supplying fuel to the evaporator tube,enhancing combustion performance under extreme working conditions such as low pressure and low fuel-air ratio.However,due to the presence of processes like fuel atomization,droplet wall impingement,and evaporation within the evaporator tube,it is challenging to directly simulate the physical processes inside the tube to obtain the spray field distribution downstream of the stabiliz-er.Regarding the complex physical processes inside the fuel evaporator tube,it proposes a simplified atomization model for the evaporator tube based on its internal flow characteristics,and under the Euler-Lagrange framework,the PaSR turbulent combustion model combined with the in-situ adaptive tabulation(ISAT)method is used to analyze the model combustor with evaporation flameholder.The flow and two-phase com-bustion of the combustor under low pressure conditions are numerically simulated.The simulation results of the cross-sectional gas temperature and combustion efficiency are close to those of the experiment.It shows that the proposed simplified evaporation tube atomization model can give a suitable distribution of fuel downstream of the flameholder and combustion field calculation.
