Electromagnetic Field Strength

Increasingly, induction heaters are being widely applied to the energy-saving light industrial equipment. But their electromagnetic radiation’s impact on the environment can’t be ignored. In the paper, several medium frequency induction heaters had been studied under different experimental conditions using E61 electromagnetic field strength analyzer, and as its supplement, the racetrack-coils induction heater had been simulated using ANSYS. According to ICNIRP guidelines, the results show that their radiation is generally in critical state, and magnetic field strength is superstandard in some areas. And countermeasures to the problems are advised.

Top Seeded Solution Growth

Three-dimensional numerical simulations were conducted for the Top-Seeded Solution Growth (TSSG) process of silicon carbide (SiC) crystals. We investigated the influence of coils frequency and peak current, and an applied rotating magnetic field (RMF) on the melt flow developing in this system. Numerical simulation results show that the Marangoni flow in the melt becomes stronger at higher coils frequencies due to the decreasing coils-induced electromagnetic field strength. Results also show that the use of external RMF may improve supersaturation uniformity along the seed if it is properly adjusted with respect to the coils-induced electromagnetic field strength. Furthermore, it is predicted that the application of RMF and seed rotation in the same direction may enhance supersaturation below the seed.
