Analysis of Heat Transfer in the Structures with Regularly Arranged Gas CavitiesIn the work, the effective thermal conductivity (ETC) of anisotropic composite material (well-conducting media with regular cavities of the air) is studied by numerical modelling. The authors examine the influence of orientation and size of the cavities on the ETC of material structure and the role of thermal conduction, convection and radiation in the heat transfer processes. For modelling,Keratermtype material was chosen. It has been proved numerically that the ETC of similar structures is lower in the case when the cavities are oriented perpendicularly to the heat flux direction as compared with parallel orientation. According to the analysis performed, the radiation heat exchange in such cavities dominates over the convective heat transfer in the observed temperature range. In the calculations of ETC in structures of the kind, convection inside the cavities can be omitted. The proposed approach allows optimisation of the arrangement and size of the cavities in similar building materials.

In the idealized theory of toroidal magnetic confinement, the plasma is supposed to be embedded in a nested set of topologically toroidal magnetic surfaces. The plasma is assumed to be stable so that all transport processes, such as thermal conduction, are determined only by Coulomb collisions between the particles. In this paper, we first compare the experimental results with the predictions of this theory. The actual energy transport rate is found to be much higher than that predicted. This is believed to be due to instability processes in the plasma although there remains the possibility that the idealized or classical theory is not complete. The role of electrostatic and of magnetic instabilities is discussed. Finally, the consequences of a simple model, in which the form of the temperature profile is fixed, are discussed.
