CFD SIMULATION OF ACCUMULATION AND EXHAUST METHANE IN CLOSED ENCLOSURES

Doru Cioclea, Corneliu Boanta, Ion Gherghe, Cristian Tomescu, Nicolae Ianc

Abstract

Anthropogenic activities involve extracting the transformation and use of natural resources. During the process of extraction of useful mineral substances on the surface or underground, particles or gases appear in the working environment resulting from the removal or natural release from the rock mass. The process of transformation of useful mineral substances is carried out on the surface in closed enclosures, and involves the use of complex technological processes. During these technological processes, gases, mists, dusts or powders of an explosive or toxic nature may be released or reach the working atmosphere. Industrial contaminants in enclosed spaces are released into the atmosphere for workers' safety reasons. In the event that workers are caught in the event of fires or explosions caused by flammable or explosive substances, morbidity is extremely high. The paper presents the CFD analysis regarding the determination of the methane dispersion dynamics during the accumulation and evacuation stages at the level of a closed enclosure.
