“…Given the conservation of the flow flux of water in the system, the flow speed in the gap is calculated using Equation (16): l " Q 3600S gap (16) During the calculation, we assume that no heat exchange occurs between the converter and its surroundings; hence, the calculated thermal power should correspond to the measured input thermal power. The measured input thermal power of the converter P in is calculated using the measured values of the input torque and rotation speed as shown in Equation (17):…”

“…Several new induction heating techniques have been reported recently. Researchers from the Universities of Bologna, Padua and Roma [13][14][15][16][17][18] used a DC high-temperature superconductive (HTS) winding to produce a high-intensity DC magnetic field, and the billet to be heated was rotated in this field. Figure 2 shows the principle of this induction heating technique.…”

“…Lubin [19] applied a two-phase superconductive winding with two operating modes. The first mode is the same as the technique presented in [13][14][15][16][17][18]. In the second mode, the winding is supplied by a two-phase AC current with low frequency, and the billet remains stationary.…”

A novel converter that can directly transform electrical, wind, hydraulic and other types of mechanical energy into thermal energy is presented in this study. First, the thermal energy of the converter is classified and then calculated by a finite element method. The eddy current distribution in the stator of the converter is also discussed. Second, the temperature field of the converter is calculated using a boundary element method. Subsequently, a thermal power-temperature coupled calculation method is presented to calculate the actual thermal power and temperature of the converter. The characteristic curves of the actual thermal power and the increase in water flow temperature are then presented based on the calculation results. Lastly, an experimental system is built, the thermal power and temperature of the converter are measured and the experimental results and the analytical calculations are compared.
