Abstract
This papers presents the results of experiments and simulation on the regularities of a high speed gas-particle flow impinging a complex target under conditions of cold spry deposition. The target consists of a substrate and an installed in front partition with conical converging/diverging perforation. Numerical simulation was performed using the ANSYS Fluent code in the mode of single particles motion (without the influence of particles on the gas flow parameters). Also, the results obtained were compared with previously investigated penetration of gas-particle flow through a mask with a cylindrical perforation.
