Abstract

 A fully three-dimensional Smoothed Particle Hydro-dynamics (SPH) code has been developed and validated with the objective to simulate primary atomization [1]. It is capable of simulating shear-driven and multiphase incompressible flows, using the weakly compressible SPH approach. With this prerequisites the simulation of a generic high pressure homogenization orifice was conducted to show the ability of the code to simulate technical relevant interfacial problems. The results are compared to Micro Particle Image Velocimetry measurements, focusing on the velocity distribution of the continuous phase and the droplet deformation and disintegration. The findings demonstrate that the code is promising regarding the simulation of the prevailing high velocities and shear driven break-up.
