Numerical Simulation of Temperature Uniformity within Solid Particles in Cold Spray

Abstract

In the numerical simulation of temperature of particles traveling in the jet flow of cold spray, the particle temperature is usually assumed uniform. This assumption is valid for spray materials with larger thermal conductivity. For spray materials with smaller thermal conductivity, however, this assumption may not be valid. This paper numerically clarifies the spray conditions for which the assumption of the temperature uniformity of the particle is no longer valid in the cold spray.
