A simplified physical model to study combustion instability of liquid rocket engines with CFD method is established in this paper. It is shown in the study that the model and the study method are both simple and efficient. In this study the gas flow in combustion chamber is described by unsteady quasi-one-dimensional Euler equations and Lagrangian method is used in liquid phase. The coupling of gas and liquid phases and the effects of vaprization /combustion of liquid spray are implicated in source terms of the equations. The influence of acoustical interaction on pressure fluctuation along with time is also investigated. The calculation is conducted with a two-step-integral predicted-correction method.
