Abstract：In order to evaluate the accuracy of different turbulence models and droplet breakup models in the simulation of high-pressure spray atomization process,based on Euler-Lagrange method and took the Spray A n-dodecane spray experiment of ECN research group of Sandia National Laboratory as a reference,numerical simulation research on high-pressure spray process is carried out.The numerical results obtained by using different turbulence models and droplet breakup models show that the numerical simulation results of the standard k-ε and realizable k-ε models in the turbulence model are closer to the experimental results when the numerical simulation of high-pressure spray atomization process is carried out.The liquid-phase penetration distance can be predicted more accurately by standard k-ε model,while the gas-phase penetration distance can be predicted more accurately by realizable k-ε model.The simulation results of KH-RT model and wave model are close to the experimental results,but the accuracy of the simulation results of KH-RT model is better.
