The spread of infectious diseases such as COVID-19 depends on complex fluid dynamics interactions between pathogens and phases, including individual droplets multiphase clouds. Understanding these is crucial for predicting controlling disease spread. This applies to human animal exhalations, coughs sneezes, well bursting bubbles that create micron-sized in various indoor outdoor environments. By exploring case studies this regard, study examines the emerging field transmission, focusing flows, interfacial turbulence, pathogens, traffic, aerosol ventilation, breathing microenvironments. These results indicate increased ventilation rates local methods can effectively reduce concentration SARS-CoV-2-laden aerosols immediate spaces individuals. In a displacement-ventilated room, both neutral unstable conditions were more effective removing breathed from air, regardless presence test subjects. However, stable may increase risk infection individuals living confined spaces. Thus, findings are useful providing practical guidance managing airborne infections.

The SARS-CoV-2 pandemic has underscored the critical importance of ventilation in mitigating indoor airborne pathogen transmission. Numerous studies have consistently observed aerosol transmission poorly ventilated environments. This article aims to comprehensively review distribution respiratory and non-respiratory contaminants across various mechanical natural systems, identify features different evaluate their performance diverse contexts, highlight primary limitations advantages. A total ten systems three were reviewed. Our analysis reveals that efficiency these varies significantly based on specific room contexts assessment criteria employed. However, as a general trend, mixing (MV) diffuse ceiling exhibit highest contaminant concentrations infection risk, while stratum yields lowest contamination levels. Notably, laminar airflow is predominantly employed cleanrooms, limited research been conducted intermittent (IV). For window-integrated fans cost-effective architectural modifications, such optimizing window placement dimensions, enhance effectiveness cross (CV) reducing contaminants. Single-sided (SSV) demonstrates poorer air quality compared MV CV, necessitating additional cleaning devices. Research efficacy windcatcher particle emissions limited. Consequently, recommendations are provided for each method minimize into occupants' breathing zones. Finally, this identifies trends underscores existing knowledge gaps within mode.

Indoor air quality significantly enhances employee productivity and well-being in offices. Existing models guidelines emphasize wind-driven natural ventilation for exchange thermal comfort but often overlook detailed airflow patterns. Understanding dynamics is crucial designing healthy offices, offering insights into processes. This information particularly valuable mitigating the impact of CO2 droplet release from multiple occupants, contributing to creation healthier office environments. study, thus, employs a validated CFD model investigate geometrical parameters on With about 150 cases representing alterations single-sided (SV) double-sided (DV) ventilation, sensitivity analysis identifies key contributors Eventually, while five major categories patterns can be identified DV (i.e., (1) without weak zone (WZ), with dominant WZ, WZ bottom side, (4) upper (5) two WZs sides), generic pattern barely seen SV cases. Moreover, cases, velocity magnitude all outputs. Leeward window geometry influences more than windward. Room dimensions ACH SF6 concentration velocity. In infected occupant location dominates changes per hour (ACH), theta impacts average contrast scenarios.
