Modelling and monitoring natural ventilation for conventional kitchens in Taiwan with transoms replaced with porous screens

For that study, numerical simulations along with full-scale laboratory experiments have been carried out to investigate the influence of the porous screens on the temperature fields, flow fields and ventilation rates within the kitchen.The air exchange rate and the age of the air in the kitchen were measured with the tracer gas concentration decay method. Concerning the understanding of the temperature and flow distributions, a CFD analysis was performed.
