A 3D flow numerical investigation was performed to explore the effects of spraying angel, structure type and rotation on the combustion property of liquid propellant in combustor AUV. The combustion flow field was simulated using κ-ε turbulence model for gas turbulent, Eddy Dissipation model for gas combustion, six-flux radiation model and particle tracking model for liquid. By Fluent software, the spraying angle effect on combustion property of liquid propellant and the flow in different type of combustors with different working parameters (1500 r/min, 1800 r/min and 2500 r/min) are simulated. The temperature and velocity of gas were computed and compared. The numerical prediction agrees well with its experimental measurement. It shows that the combustion property of liquid propellant becomes serious and efficiency in the non-axisymmetric sudden-expansion structure of combustion chamber with 90° spraying angel. The axial size of combustor can be reduced. Appropriate rotation makes the fuel´s combustion faster and more effective in the same volume combustor, which is benefit to combustion process. And, rotating makes the pressure enhanced in combustor. Thus, the research is expected to lay a foundation for design and improvement of AUV combustor.
