摘要: A three-dimensional model of a Cold Gas Dynamic Spray system with peripheral nonaxisymmetric powder feeder is studied in this work. It found that the stagnation pressure alternates for different substrate standoff distances due to nature supersonic flow interaction substrate. One can find optimum location any given operating condition, which results minimum buildup on The analysis sheds more light complex gas and particle fields generated injection process. In addition, allows us further investigate effect practical shapes (such as convex concave) field consequently determine conditions deposit coating particles.
