Abstract
Exposure to cooking emissions could increase the risk of adverse health effects such as lung cancer. Even though hood operation could be an effective intervention strategy, information on how ambient temperature would impact the hood performance and pollutant distribution is limited. Therefore, the objective of the study is to evaluate the impact of ambient temperature on the performance of four commercial kitchen hoods with distinct shapes by validated Computational fluid dynamics (CFD) models. The Computer-Aided Design (CAD) model and the boundary conditions were set based on the experimental measurements. The results showed that both the hood shape and ambient temperature would affect the flow field and further influence hood performance, and the validated models could be applied to predicting the performance of new kitchen hoods with different environmental and hood operation conditions.
