Experiments on powder entrainment have been carried out to study the influence of different variable parameters on incipient mass flow rate. A semi-empirical model was established by taking into account many affecting parameters, including: initial total pressure, particle mean size, throttling orifice area and powder volume fraction. This model could be used to predict the incipient mass flow rate with particle mean sizes from 10 μm to 100 μm. By comparing the relative error between the semi-empirical model and previous model, the results show that the semi-empirical model has higher prediction accuracy than previous model.In the progress of particle entrainment, there exists three stages: flow-out stage with gas (stage I), flow-out stage with large amounts of particles (stage II), and flow-out stage with small amount of particles (stage III). The result of stage I shows that there exists a pickup delay for particles, which is good for the ignition sequence matching research of powder engine.
