A Study on Ignition Delay of Diesel Fuel Spray via Numerical Simulation

摘要

To investigate the ignition process in a diesel spray, the ignition in a transient fuel spray is analyzed numerically by a discrete droplet spray model (DDM) coupled with the Shell kinetics model at various operating conditions. Predicted results show that the fuel mixture injected at The start of injection, which travels along midway between The spray axis and the spray periphery, contributes Heavily to the first ignition in a spray.
