17. Simultaneous Solutions of Coupled Thermal Airflow Problem for Natural Ventilation in Buildings
Published: 5/11/2011
Authors: Steven J Emmerich, William S Dols, Liangzhu (Leon) Wang
Abstract: Natural and hybrid ventilation are sustainable building ventilation strategies, where airflow is driven naturally by thermal buoyancy and/or wind forces other than pure mechanical means. The simulation and design of these systems thus need to conside ...
