A Computational Fluid Dynamics (CFD) study of an airflow in a single storey building integrated with a combined system of wind catcher and solar chimney

The biggest challenge in the 21st century is global warming,which seriously threatens humanity.The Building sector,which accounts for 40 % of global energy use and greenhouse gas emissions,plays a key role in this threat. In this regard,the effects of cooling systems can not be ignored if,together w...
