摘要：

In this paper, we address the issue of accurate modelling of experimental data in order to provide numerical settings for Reynolds averaged Navier-Stokes (RANS) numerical simulation of the gas-gas jet generated by a single-hole diesel-like injector. Since experimental operating conditions usually do not document the inlet boundary conditions, both subsonic and supersonic inlets have been considered for the numerical simulation. For the supersonic case, a two-dimensional (2D) cartesian mesh has been used. For this case, good agreement with experimental jet penetration is obtained when realistic time evolution of the inlet pressure is prescribed but the jet shape is different compared to the experimental one. For the subsonic case, the axisymmetric RANS simulation allows to obtain the best agreement between experimental and numerical jet penetrations, head jet shapes and fuel density profiles.
