Abstract
Gas flows in the gravity field through the porous objects with energy sources, which may originate from the natural or man-caused disasters, are investigated. An OpenMP version of the parallel algorithm has been developed for calculating unsteady 2D gas flows through porous self-heating media of complex subsurface geometries. The structure of the sequential algorithm and the transition from it to the OpenMP version are described; the performance and efficiency of parallelization are analyzed. Unsteady gas flows through axisymmetric porous self-heating objects with a partial closure of the object outlet (with a top cover) are investigated by means of the developed parallel algorithm. The influence of the partial closure of the object outlet on the cooling process of the porous objects with a nonuniform distribution of heat sources is analyzed.
