The Application of the Solar Chimney for Ventilating Buildings
… to demonstrate the potential applications of the solar chimney for the naturally ventilating a building. Computational fluid dynamics (CFD) was used to model various room configurations to assess ventilation strategies. A parametric study of the solar chimney system was executed, and …

An experimental investigation of a solar chimney natural ventilation system
Natural ventilation driven by a solar chimney attached to a single-room building was studied experimentally using a small-scale model. The experiments were performed using a recently developed fine-bubble technique in which fine hydrogen bubbles are produced electrolytically in salt solution to …

Numerical Analysis of Airflow and Output of Solar Chimney Power Plants
Computational fluid dynamics was used to simulate solar chimney power plants and investigate modeling techniques and expected energy output from the system. The solar chimney consists of three primary parts: a collector made of a transparent material such as glass, a tower made of concrete located …

Exploring Alternative Designs for Solar Chimneys using Computational Fluid Dynamics
Solar chimney power plants use the buoyancy-nature of heated air to harness the Sun's energy without using solar panels. The flow is driven by a pressure difference in the chimney system, so traditional chimneys are extremely tall to increase the pressure differential and the air's velocity. …

Low energy cooling in multi-storey buildings for hot, arid climates
… existing ones. It uses evaporative coolers and solar chimney systems at daytime. It also uses night-time forced ventilation to cool the ordinary slab. The second can be applied in new buildings. It uses evaporative coolers and solar chimney systems at day-time. It also uses night-time forced …

Numerical study of the thermal performance of solar chimneys for ventilation in buildings
… such type of natural ventilation system is the solar chimney which can either be roof-mounted or wall-mounted in buildings. The aim of this study was to develop a mathematical model for assessing the thermal performance of roof-mounted (inclined) and wall-mounted (vertical) solar chimneys. The …

Solar induced ventilation in the Algerian and similar climates
… and can be promoted by a sun-warmed cavity or 'solar chimney' added to a building on the sunward side. The cavity may be of any material of high thermal capacity. Heat from the sun is stored within the walls forming the cavity and heats the air within. The cavity is closed at the top and bottom …

Numerical Modeling and Optimization of Power Generation from Shrouded Wind Turbines
… converting abandoned or unused farm silos into solar chimneys with low cost shape modification of the chimney to further augment the power generation. The most effective, simple and low cost shape modification is found to be a diffuser added to the top of the silo, which can increase the power …
