Iranian wind towers "Badgir" works thanks to natural driving forces, such as differences in temperature between a building and its environment. By evaporation, convection and natural air currents, we can manage the internal thermal comfort of the local interior environment. The air movement is carried out by the process of pressure and extraction....

A wind tower (Badgir in Persian) captures wind from any direction and guides it to the occupant's zones. Built on the roof, the wind tower has been used for many centuries, employed at different heights, ranging from 1 m to 33 m. These towers are a zero carbon cooling technology. This paper describes four steps: climate search in Iran; various spec...

In this study, smoke visualization approach was used to investigate the main flow features around and inside various types of one-sided wind-catcher models. Wind-catcher models with flat, inclined or steep and curved roofs are used in the experimental flow measurement and flow visualization. Wind-catchers play an important role in creating natur...

Cette recherche porte sur l’histoire et l’évaluation des performances des tours à vent (Badgir en persan). En termes de construction, les tours à vent se sont développées de manière considérable au cours de l’histoire. Le matériau de construction utilisé a été en grande partie l’adobe : mélange de terre d’argile, de paille et d’eau. Ce matériau nat...

This paper concerns the characterization of the raw materials used and the study of the fresh state, the compressive strength, the thermal analysis, the transport properties and the chloride penetration by different conditions as immersion and tidal condition in 4 formulations of self-compacting concrete (SCC). The control concrete corresponds to a...

Article
Full-text available
In this paper, the influence of an upstream structure on the flow pattern within and around the wind-catcher is experimentally investigated by smoke flow visualization techniques. Wind-catchers are an important part of natural ventilation in residential buildings or public places such as shopping centers, libraries, etc. Wind-catchers might be also...
