Conclusions• The proposed PC is simulated and a self-sustained pulsecombustion process is achieved.• The predicted phase delay between gas pressure , temperature,and heat loss is consistent with phase relation described byRayleigh’ criterion• The predicted PC have a pulse frequency <strong>of</strong> 250 Hz, exitvelocity <strong>of</strong> 40~125 m/s, pressure amplitude <strong>of</strong> 12 kPa• The novel CFD model using a dynamic mesh have an ability tosimulate the dynamics <strong>of</strong> inlet valve and its resulting fuelinflux.• The coupling <strong>of</strong> dynamic <strong>of</strong> the flapper, influx <strong>of</strong> fuel, acousticpressure was simulated by novel CFD model
