【Abstract】 It is very important for the applications of industrial microwave heating to know the temperature variation during the heating procedure. The temperature variation inside the water irradiated by microwave is simulated using FDTD coupled with heat transport equation (HTE). Numerical results show that time scaling factor has a significant effect on the temperature variation of the water. Moreover, the numerical results of temperature are degraded if the time scaling factor is too large. The optimum range of the time scaling factor is suggested according to the numerical results.更多还原
