Three-Dimensional Numerical Simulation of Inductively Coupled Plasma Generator

Taking the inductively coupled plasma wind tunnel that studies the blackout of reentry vehicle in the aerospace field as the research object, the discharge state of the plasma generator under large size, high power and high pressure is studied. Through the multi-field coupling of turbulent field, electromagnetic field and temperature field, a three-dimensional numerical simulation of the rotating inlet flow and heat transfer process of an inductively coupled plasma generator with a power of 1MW is carried out, and the distribution law of the magnetic field intensity, the temperature and velocity in the tube are obtained. At the same time, the physical mechanism of the formation of each distribution and the influence of rotating intake on the plasma discharge characteristics are analyzed. These provide basic theoretical data for the optimization design of the inductively coupled plasma wind tunnel and its industrial application.
