microwave heating numerical simulation

In microwave heating field, the establishment of high temperature heat transfer, mass transfer model of microwave reactor material, through the numerical simulation and experiment test, on the one hand can accurately understand the high temperature microwave field and the temperature distribution in the reactor, thus to control the heating process optimization of material On the other hand, can further study the effects of external conditions change of reaction process, get the general rule of microwave heating material process, realize the normal operation of the high temperature reactor under the condition of high temperature.

At present, most of the numerical simulation of microwave heating temperature is concentrated in the low power, low temperatures, single mode, small volume and the single material aspects, such as in heating, fresh food and wood drying. In the applications, the material is not in the heating process temperature range, the electromagnetic parameters and thermal parameters did not change significantly, the numerical simulation can be approximated as a constant, the heating process is linear, numerical simulation is relatively simple.



In a microwave reactor, on the one hand with the material temperature rises, the dielectric constant and conductivity of electromagnetic parameters and specific heat, thermal conductivity, heat and other physical parameters change accordingly, the heating process is non-linear. On the other hand, more than a microwave reactor material is a mixture of dielectric constant and thermal properties of the material difference between the larger and difficult to measure. Therefore, the microwave heating temperature distribution Numerical simulation of a serious lack of effect of material dielectric constant and variable temperature and thermal parameters and other basic data.
