Numerical simulation of a steady, nonevaporating hollow-cone spray interacting with a concentric annular air jet has been performed using the discrete stochastic particle method in KIVA. The spray characteristics such as the Sauter mean diameter (SMD), mean droplet velocity, liquid volume flux, air/liquid mass ratio, and droplet number density have been obtained and compared with measurements involving different airflow rates in large and small annuli. Overall, satisfactory agreement is observed between calculation and experiment except for the deviation in the downstream SMD arisingfrom uncertainty in tbe size distribution function at injection, and inaccuracy in the averaged spray parameters due to tbe small volumes of axisymmetric 2-D sector meshes close to tbe axis.
