Research on Combustion Property with Different Propellants in Underwater Vehicle Combustor
In order to find out the combustion property in the combustor of the underwater vehicle with two different propellants, OTTO-II monopropellant and HAP+OTTO-II+H2O tripropellant, the two-phase turbulent combustion processes in rotation combustor were numerically simulated by FLUENT. There were three models used in the simulation, which consist of gas turbulent model with k-e model, eddy dissipation model for gas combustion and discrete droplet model for liquid. The distribution of static temperature, turbulent rate of reaction, concentration of CCh, concentration of CO and particle motion trajectory were computed and compared. The results of numerical simulation show that the combustion characteristics of tripropellant are better than characteristics of monopropellant. The tripropellant comprise inert species H2O, so the slow evaporation of tripropellant makes the burning stability be worse.
