This paper presents plasma thermal jet simulations with substrate interaction. In this work, two dimensional plasma thermal jet simulations will be presented using the ANSYS-CFX code with taking into account the interaction fluid-substrate during thermal spraying. Two models of turbulence are used such as the shear stress transport K-? (SST- K-?) and Re-Normalization Group (RNG- K-?). The governing parameters of the problem under study are the plasma gas power, the nozzle exit temperature and velocity profiles, the plasma jet temperature and velocity fields and the substrate temperature. The experimental and numerical results are presented in order to carry out a comparison between these results. Moreover, transient simulations will be also treated for different x-positions and different values of time. The distribution of temperature of the substrate will be also presented.
