Jet impingement against surfaces is uses in several industrial applications, including the internal cooling of turbine blades. Coolant used for blade cooling is air bleed from a compressor and is laden with particles.

A numerical simulation of a particle-laden impinging jet is here proposed, aiming at studying and analysing the effect of surface curvature on flow field, particle motion and deposit formation. To this aim, an impinging jet on a flat and a curved walls is considered. Flow motion is be solved using Direct Numerical Simulation, thus no additional model is needed for turbulence effect on particle motion.

Results show that the deposit patterns follow some secondary flow structures, showing a series of peaks forming according to those structures. The peaks are present in both the main orthogonal direction of the jet, but they are not symmetrical due to surface curvature.
