Numerical simulations showed the axial velocity in the precessing flow were decreased significantly because of the entrainment of ambient air. The swirling motion, the wall attachment effect and the reverse flow were also found in the numerical flow field. It is shown that the simulation results of the precessing jet flow accord well with the analysis and the previous work.
