摘要	A numerical model based on k - Ε turbulent model and EBU-Arrhenius turbulent combustion model is applied to simulate the venting process in cylindrical vessel (L/D =5.6).The flow fields of venting occurred at venting pressure of 0.02 MPa through different vent area show that during venting process the flame propagation and deformation is intensified by a venting induced flow; vent area is the main factor for determining the vent inducing flow. Small vent area and low venting pressure produce weak venting induced flow; large vent area usually produces a relatively strong venting induced flow; even the venting pressure is low. The squish flow and reverse flow which induced the velocity gradient is the possible mechanism of tulip flame.
