A complete two-dimensional self-consistent model was used to calculate the velocity field and the temperature field of the plasma. The trajectory and heating history of the particles were calculated using the particle trajectory model. However, in the continuous, momentum and energy governing equations of the plasma, , Velocity and energy enthalpy changes caused by the source of the project, taking into account the particle motion and heating of the plasma velocity and temperature fields; particle trajectories and heating history calculation, consider the fluid resistance and thermophoretic force On particle motion and heating; and iteratively calculates the velocity and temperature fields of the plasma and the motion and heating of the particles. The calculation of aluminum particle and argon plasma flow shows that the interaction between particles and high-frequency induction thermal plasma flow not only affects the trajectory and heating history of the particles, but also has an influence on the velocity field and the temperature field of the thermal plasma flow Significant influence
