Axisymetric lattice Boltzmann (LB) model is developed to investigate the interaction of momentum and heat between plasma hot gas and Alumina powders. The plasma flow is simulated using a double population lattice Boltzmann model and the plasma-particles interaction is modeled based on a Lagrangian approach for the motion and heat transfer equations. The present results show that the LB method is an efficient and powerful tool to comprehend and explain the very high complexity of the plasma jet physics as well as it preserves effectively the computational cost. The present results for the centerline temperature and velocity profiles agree well with the previous experimental and various numerical approaches findings. Furthermore, our results for the plasma-particles interactions are in good agreement with the Finite-Differences results of the Jets&Poudres code for particles motion and heat-up.
