Abstract: The article presents an investigation of gas flow that occurs under typical for cold spraying conditions when supersonic gas jet, that exhausts from De Laval nozzle, and impinges on mask with a round perforation, behind that substrate is placed. Numerical simulation was made using software ANSYS Fluent. Shadowgraph was used to obtain images of gas flow. The results obtained were analyzed and compared. [ABSTRACT FROM AUTHOR]
