The present study is conducted to simulate the multi-component chemical reactions of a turbulent argon-hydrogenplasma jet flowing into the surrounding atmosphere under typical operating conditions. Based on the initial sprayingprocess parameters, the temperature, velocity profiles and the basic chemical species at the nozzle exit arecalculated, and then used for the boundary conditions of the next step, where the chemical reactions in the multicomponentplasma jet are calculated by employing the Eddy-Dissipation model and the Realizable k-ε turbulencemodel. As the result of the calculation, the distribution of the mole fractions of the products as well as thetemperature and velocity distributions is discussed. The approach presented in this paper will be theoreticallyhelpful to perform further analysis of the interaction between the plasma and the particles.
