Special Issue Information

Dear Colleagues,

The development of the urbanization process may affect atmosphere pollution, as urban constructions change natural geomorphologic conditions. Dispersion of toxic gases due to natural or industrial accidents may lead to potentially dreadful consequences. Therefore, measuring the ventilation rate is crucial to ensuring the control of emission of pollutants in households as well as buildings in rural areas such as greenhouses or animal houses. To prevent the effects of uncontrolled emission of pollutants, different approaches have been introduced. For instance, mathematical models have been developed for air quality/condition assessment. Additionally, to assist in decision making and planning of the placement of hazardous zones, computational tools are applied. Furthermore, simulation using computational fluid dynamics (CFD) techniques can provide detailed data on the prediction and visualization of spatial dispersion. This Special Issue is addressed at research studies focused on different aspects of air pollution and its treatment in developing countries.

Air pollution is a global problem that is responsible for more than four million premature deaths each year. Air exchange in ammonia engine rooms is a priority for normal operating conditions, as well as in the event of an emergency release. A numerical approach with the use of computational fluid dynamics techniques can provide detailed data, such as spatial gas dispersion. Therefore, the objective of this study was to prepare a mathematical tool for the assessment of ammonia distribution in an engine room equipped with forced ventilation as a prediction tool for dangerous industrial setup working configurations. This study analyzed the uncontrolled release of ammonia during the production process in an engine room using Ansys Fluent software. It was observed that emergency ammonia leakage of 0.1 kg/s in the assumed air flow poses a great threat to the mechanics. In many simulated scenarios, ammonia spread to the entire building. Moreover, the mass fraction of ammonia was the highest in the gas stream right after its release. After being released, ammonia often accumulated in the ceiling zone, and in inactive exhaust chimneys, air inlets, and doors. It was observed that the effectiveness of the ventilation analyzed depended on the number of active air vents and exhausts, as well as their spatial distribution throughout the building. Full article
