Abstract A new rotating induction heater is proposed, and its mathematical and physical model of 3-D fluid and temperature coupling field are established according to the characteristics of fluid flow and heat transfer. The equivalent coefficient of heat conductivity for airgap and the coefficient of heat transfer for surface of main components are given based on empirical formulas. The 3-D fluid and temperature coupling field are numerically calculated using finite volume method. The temperature rise of water and the temperature field in heater are determined under different working conditions. Experiment test are implemented on experiment platform for heating water by the heater. Some useful conclusions are obtained by comparing the calculation result with test value.
