Численное исследование конвективно-радиационного теплообмена в замкнутых областях на основе решёточного метода Больцмана

Abstract

In this study, the benchmark problem of convective-radiative heat transfer in a closed square cavity has been solved on the basis of the lattice Boltzmann method (LBM). In addition, a similar problem has been solved using the finite difference method. The data obtained in various numerical methods have been compared with the data of other authors. The obtained thermohydrodynamic characteristics are in good agreement, which indicates the possibility of applying mesoscale method (LBM) to problems of natural convection and radiation in various fields. In addition, the lattice Boltzmann method allows calculations to be performed faster than classical grid methods.
