Modelling and Monitoring Natural Ventilation for Conventional Kitchens in Taiwan with Transoms Replaced with Porous Screens

This study analyses the ventilation efficiency and indoor air quality of conventional kitchens in Taiwan, in which the transoms were replaced by screens of various porosities. Numerical simulations and full-scale laboratory experiments were performed to investigate the influence of the porous screen...

description This study analyses the ventilation efficiency and indoor air quality of conventional kitchens in Taiwan, in which the transoms were replaced by screens of various porosities. Numerical simulations and full-scale laboratory experiments were performed to investigate the influence of the porous screens on the temperature fields, flow fields and ventilation rates within the kitchen. The tracer-gas concentration decay method was applied to measure the air exchange rate and the age of the air in the kitchen. Meanwhile, computational fluid dynamics (CFD) analysis was performed to obtain a detailed understanding of the temperature and flow distributions.
