Rotating orifices and cavity are important parts of the air system of gas turbine engine, and their transient response might induce dangerous instantaneous transient load. To investigate the transient evolvement of the cavity with rotating orifices, a CFD model of the cavity with rotating orifices was built to research the cavity in front of the rotating orifices. Based on the steady flow characteristic of the rotating orifices, a transient one-dimensional model was built to simulate the transient process. The comparison of the results between the one-dimensional model and the CFD model shows that the former can conduct the transient process simulation satisfactorily and satisfy the elementary engineering needs. Finally, the analysis of the reason for the result errors of one-dimensional model is presented in this paper.
