개요
The spread of infectious diseases among domestic animals has become a major concern as livestock farming grows increasingly large-scale and high-density. Despite this,research on using UV disinfection systems in livestock environments remains limited.
This study aims to apply a UV disinfection system to a mechanically ventilated pig house using Computational Fluid Dynamics (CFD) simulation. A Discrete Ordinate (DO) model was used to analyze the radiation transfer, while a Discrete Phase Model (DPM) was employed to calculate the UV dose on individual particles. Results showed that an array of lamps aligned parallel to the airflow produced the highest dose distribution, effectively inactivating a wide range of viruses. Furthermore, a lamp power of 17 W achieved over 90% disinfection efficacy against common swine pathogens.
This study provides insights into the optimal lamp arrangement and disinfection efficiency under various environmental conditions in livestock housing.
