| Abstract [eng] |
Indoor air quality is one of the most important factors for a good quality of life. Indoor air quality can be affected by many different factors, one of them being tobacco products. Heated tobacco products are a new and widespread alternative to traditional cigarettes, but each new product on the market should be carefully studied to characterise emissions into the environment and thus potential impacts on air quality and bystanders. The aim of the Master's Final Degree Project was to develop a computational fluid dynamics model of indoor air pollution caused by tobacco heating products and to validate it using experimental data. The literature review provides an overview of combustible tobacco products, the principle of operation, the analysis of chemical emissions, indoor concentrations, the assessment of health effects and the applicability of computational fluid dynamics to calculate the established model, an overview of the specifics of the modelling, and the choice of SolidWorks software. The methodological part describes the methodology, data, system model, research design and sequence of work. Different aerosol particle sizes have been selected for the source design: 50nm, 60nm, 70nm, 80nm, 90nm, 100nm. In the results part, the simulation of different ventilation modes and the modelling of the selected aerosol particles to a breathing human being was carried out and the results are summarised. |
