Sažetak
Current guidelines on control measures for preventing the spread of coronavirus show no consensus regarding the impact of ventilation on virus dispersion in a closed environment. Even though much research has been done to define this impact, the type of ventilation and airflow rates most appropriate for specific applications remain unclear. Several key aspects are crucial in ensuring the exactness and validity of the research: ventilation parameters, the airborne transmission modeling technique, and the focus of this study which is the human models. This paper aims to give practical guidelines for a simplified human model designed for experimental and numerical research. Here we show that a simplified human body geometry combined with a heat source can achieve an appropriate balance between feasibility and accuracy. The most important features of the human model are discussed and explained thoroughly, with the temperature stratification above the model of particular importance. We believe that the proposed guidelines contribute to better consistency and feasibility of further research and, consequently, lead to more suitable safety measures for the current and future pandemics.
