The present paper reports the development of Finite Particle Method (FPM) in the framework of 3D impinging jet simulations. The FPM kernel has been proposed recently in the literature to improve the consistency of standard SPH. Moreover, a new particle shifting method is proposed to mitigate the particle clustering issue. The influence of particle spacing, maximum CFL number and different particle shifting methods are investigated in the case of a water jet impinging perpendicularly on a flat plate. The results are compared to available measurements and grid-based CFD simulations.
