EN In this paper the parallel computing of conjugated heat transfer both by radiation and conduction in a two-dimensional lightweight thermal insulation layer was analysed. It was assumed that the medium can emit, absorb and isotropically scatter radiation. Its walls were opaque, absorbing, emitting and reflecting diffusively. At first, the problem was numerically solved by carrying out the sequential calculations. The radiative transfer equation was discretised by the Finite Volume Method. For the heat conduction equation the Alternating Direction Implicit Method was applied. Next the Domain Decomposition Method was used to perform the parallel calculations by dividing the whole domain into two and four sub-domains. Influence of different factors on differences between the results obtained from the parallel computing and from the sequential calculations were studied. Finally, the parallel computing speed up and efficiency were analysed together with factors affecting them.
