“…To check the correctness of the velocity simulated in our study, we consult several relevant references. [12,25,42] Approximate values of the simulated velocity are found for the high power ICPs. [25,42] For example, Vasil'evskii and Kolesnikov [25] simulated an air ICP flow under similar working conditions: the nominal input power P = 90 kW, f = 0.44 MHz, p = 10 kPa, m = 2.8 g/s.…”

“…[25] Although their input power is lower than P = 160 kW in our case 1, their working pressure and mass flow rate are also lower than p = 15 kPa, m = 16 g/s in case 1, respectively. Lu and Feng [12] has reported that the plasma velocity decreases as the pressure and the mass flow rate increase. Thus, for case 1 the simulated maximum velocity (110 m/s) has the same order of magnitude as the one (150 m/s) reported by Vasil'evskii and Kolesnikov.…”

“…They also employed numerical simulation and equivalent circuit analysis to optimize the design and analysis of a high power ICP torch system with a vacuum tube oscillator. Lu and Feng [12] investigated the effects of the operating parameters on the ICP properties by a non-equilibrium magnetohydrodynamic model. Their numerical model can aid in determining the optimal conditions for producing the ideal plasma.…”

We take the established inductively coupled plasma (ICP) wind tunnel as a research object to investigate the thermal protection system of re-entry vehicles. A 1.2-MW high power ICP wind tunnel is studied through numerical simulation and experimental validation. The distribution characteristics and interaction mechanism of the flow field and electromagnetic field of the ICP wind tunnel are investigated using the multi-field coupling method of flow, electromagnetic, chemical, and thermodynamic field. The accuracy of the numerical simulation is validated by comparing the experimental results with the simulation results. Thereafter, the wind tunnel pressure, air velocity, electron density, Joule heating rate, Lorentz force, and electric field intensity obtained using the simulation are analyzed and discussed. The results indicate that for the 1.2-MW ICP wind tunnel, the maximum values of temperature, pressure, electron number density, and other parameters are observed during coil heating. The influence of the radial Lorentz force on the momentum transfer is stronger than that of the axial Lorentz force. The electron number density at the central axis and the amplitude and position of the Joule heating rate are affected by the radial Lorentz force. Moreover, the plasma in the wind tunnel is constantly in the subsonic flow state, and a strong eddy flow is easily generated at the inlet of the wind tunnel.

The physical characteristics for the study of two-dimensional inductively coupled plasma (ICP) discharge with different designs of copper coil and gas composition are presented in this paper. And this numerical model is a typical inductively coupled plasma discharge. Compared with former publications studying in ICP discharge, our simulation results indicate some new discoveries. First, the inductive coil gaps are arranged at different distances and their physical properties are studied in argon environment. The maximum electron density, electron temperature and macroscopic gas temperature are obtained at the best coil gap distance for discharge. Then, the inductive coils on the quartz tube without changing the coil gaps between the coils are placed in different positions and the discharge properties are also studied in argon environment. The maximum electron density, electron temperature and macroscopic gas temperature are obtained in the best position for discharge respectively. Finally, the physical characteristics of the ICP discharge in different gas compositions (other physical parameters were unchanged) are studied and the related important chemical reactions are also been described. It is concluded that the best discharge effect of argon gas is obtained under the same discharge conditions.
