About the theory of heat by electromagnetic radiation environments
The heating of different environments in the electromagnetic field is characterized by the presence in the environments being heated by volume distributed heat sources. Distributed in terms of the nature of heat sources increases the heating rate and improves the heat (more uniform heating). In this work, solutions of heat conduction equation, which describe temperature distribution in the environment heated by electromagnetic radiation in case of fixed density of heat sources, are received. Density of heat sources defines by electric field intensity and frequency and dielectric parameters of the heated environments. The case of penetration depth great exceeds linear dimensions in heating area is considered. For plane one-dimension geometry, boundary problems of first, second and third types are considered, which correspond different boundary conditions on a surface: isothermality (temperature is fixed), adiabaticity (lack of heat flow) and presence of heat convective flux. Unlike well-known cases, in this one a more general condition is concerned, movement of the heated environment and heat transfer with surrounding environment in thermally skim approximation are taken into account. Consideration of these factors allows you to simulate the heat transfer in process plants conveyor microwave heating. Also in this work, integrals of the special functions were obtained and showed. These integrals are of interest in the solving problems of heat-and-mass transfer described by parabolic equations. Obtained solutions allow analyzing heating modes of the dielectric environments by electromagnetic radiation with a glance to characteristic features due to movement of the heated environment, heat transfer with surrounding environment and the boundary condition difference.
