this paper is an attempt to numerical modeling and experimental study of air flow in the yazdi wind-towers. wind towers has been known as one of the most effective climatic elements in iranian traditional architecture. this paper is an attempt to evaluating yazdi wind-tower to discussion the two main questions: 1. what is the role of orientation of wind-towers span, regarding to climate and hei...

Insufficient airflow in the cavity of Double Skin façade (DSF) systems has resulted overheating risk and resulting reduction thermal performance cooling dominant climates. Previous research focused more on buoyancy-driven natural ventilation, there is a lack utilising wind-driven ventilation as force for heat dispersion from cavity. Additionally, geometrical features wind direction influential ...

Hydroelectric power plants’ open-type surge tanks may be built in mountains subject to the provision of atmospheric air. Hence, a ventilation tunnel is indispensable. The air flow in the ventilation tunnel is associated with the fluctuation of water-level in the surge tank. There is a great relationship between the wind speed and the safe use and project investment of ventilation tunnels. To ob...

One of the main architectural characteristics in the central area of Iran is the relation between life and climatic conditions; e.g., the four-seasonal house which is a typical kind of the central-yard house. As the climate of Isfahan is more pleasant than other desert regions in the central part of Iran, wind towers are replaced with skylights to ventilate the pool area of hoze-khane. So far, ...

Unlike many other engineering products, where a prototype model is built, tested and modified, buildings can only be examined after they are built. It is then too late to correct any design mistake. Therefore, architects depend on scaled models to simulate as close as possible the final product and test the design. The currently available approach for students as well as professionals to simula...

Enhancing the ventilation performance of energy-efficient buildings with single-sided openings is important because their ventilation performance is poor and strongly depends on the wind conditions. We considered an overhang as a potential building façade for improving the single-sided ventilation performance. We performed numerical simulations of three-dimensional unsteady turbulent flows over...
