- G0700-3-2 In-cylindedr Gasflow Simulation at Low Valve Lift Opeation by Gas-Parcel Method
抄録
A simulation method was proposed to predict in-cylinder gas flows under low valve lift operating condition. Generally a simulation by the voxel method under low valve lift condition requires enormous nodal points to represent a minute valve opening. The gas-parcel method was applied to treat inflow from the intake valve openings and the initial conditions of the gas-parcels were given by the 1-dimensional cycle simulation based on a plant model. The mass, momentums and energy were transferred from the gas-parcels to the continuum gas-phase in the cylinder. Because gas-parcels represent inflow from minutes valve openings, detailed mesh division is not necessary by this method. The simulation results were compared to the in-cylinder velocity vectors obtained by using PIV. The futures of the gas flow pattern under the low valve lift condition were reproduce by the simulation so it was confirmed the proposed method was useful for in-cylider gas flow simulation with low valve lift conditions.
