Solar chimney and building ventilation

Enhancement of stack ventilation in hot and humid climate using a combination of roof solar collector and vertical stack

“…The leeward position of outlet could assist the stack ventilation [15]. During the experiment, the prevailing wind direction recorded was the SoutheWest and SoutheEast.…”

“…This is due to the higher sun altitude in the hot and humid climate [1]. Nevertheless, the roof solar collector has a drawback in which the stack height is restricted by the roof slope [1,15]. There are also studies executed on the potential of Trombe wall [4,10] and solar chimney [5,11] in the hot and humid climate.…”

Numerical investigation of transient natural convection in a vertical channel-chimney system symmetrically heated at uniform heat flux

“…The reservoirs are employed in order to simulate thermal and fluid dynamic behaviors far away from the inflow and outflow regions. The geometry studied in this numerical investigation is important in different applications, such as in electronic cooling [9,[11][12][13][14]18,23,24,27] and in building ventilation and houses solar components [8,10,11,16,17,[31][32][33]. The main differences between the present investigation and the study in reference [19] is the considered geometrical configuration.…”

Enhancement of natural ventilation of a novel roof solar chimney with perforated absorber plate for building energy conservation

“…Efficient air ventilation and acceptable air quality are of great importance in many residential and commercial buildings [1,2]. Increasing the awareness of the need of energy demands and environmental-friendly design for buildings throughout the world has induced researchers and engineers to improve the methods of ventilation for buildings by utilizing renewable energy such as solar and wind energy [3][4][5].…”
