In a cold spray research, we can simulate particle velocity and temperature by a numerical simulation. From the theoretical point of view, we can recognize two parameters which combine particle diameter and material properties. One is particle-velocity related parameter, which is the particle diameter multiplied by particle density, as in the equation of particle motion. The other one is particle-temperature related parameter, which is the squared particle-diameter multiplied by the particle density and specific heat, as in the equation of particle energy. This paper investigates particle velocity and temperature of cold spray for a wide range of particle diameters and material properties of particles by numerical simulation. The results show that when the simulated particle impact velocity is plotted against particle-velocity related parameter the distributions of particle impact velocity are almost identical regardless of the difference in spray material. It is true for particle impact temperature against the particle-temperature related parameter.
Summary: This paper investigates particle velocity and temperature of cold spray for a wide range of particle diameters and material properties of particles by numerical simulation. The results show that when the simulated particle impact velocity is plotted against particle-velocity related parameter the distributions of particle impact velocity are almost independent of spray material. It is true for particle impact temperature against the particle-temperature related parameter.
