Abstract

This study investigates the transmission of airborne infectious diseases in shared-office spaces, a critical concern post-COVID-19. Focusing on disease transmission dynamics similar to COVID-19, we utilize Computational Fluid Dynamics (CFD) to simulate airflow and pathogen dispersal in an educational facility's shared office space, incorporating ceiling-mounted exhausts, supply diffusers, and desk fans. The research critically examines the placement of diffusers and their impact on air distribution, vital for effective ventilation and contaminant control. A steady-state simulation approach explores different diffuser configurations on airborne pathogen distribution. Using the Discrete Phase Model (DPM), we model cough-generated droplet dispersion, representing pathogen transmission. The findings reveal the spatial and temporal distribution of airborne pathogens, showing how varied ventilation strategies can significantly affect infection probabilities. This research balances thermal comfort with reduced infectious disease spread risk, offering vital insights for designing safer indoor environments amidst public health challenges. It contributes to the understanding of airflow and contaminant control, aiding public health strategies against airborne diseases.
