The directional openings direct cool winds by keeping the shaft against the wind open. The cool air descends and circulates, and then the warm air rises and escapes. In areas without wind, the towers also function as a thermal chimney by creating a pressure gradient and letting the dense warm air escape upwards.Aug 18, 2022.
How does an Arabic wind tower work?
The wind tower is also referred to as a 'wind catcher' for its ability to catch fast moving breezes. As warm air enters the top of the barajeel, it cools inside the tower. Once cooled, the air eventually lowers, bringing relief for those at the bottom of the tower inside the home..
What is the architecture of a wind tower?
Wind tower is a key element in traditional architecture of Iran. It is seen in settlements in hot, hot-dry and hot-humid climates. They look like big chimneys in the sky line of ancient cities of Iran. They are vertical shafts with vents on top to lead desired wind to the interior spaces and provide thermal comfort..
What is the architecture that channels wind?
Wind towers are designed to catch and channel the prevailing wind. As air flows into the tower, it creates a pressure difference that draws air out from the building. This movement of air facilitates the exchange of indoor and outdoor air..
What is the principle of wind tower?
The windtower essentially creates a pressure gradient to draw air through the building . Windtowers topped with horizontal airfoils have been built to enhance these pressure gradients. The shape of the traditional shuksheika roof also creates suction as wind blows over it..
A Windcatcher, also known as wind tower, wind scoop, Malqaf, or Badgir, is a traditional cooling architectural element that has been used for thousands of years in countries with severe hot climates.Nov 3, 2021

The way these towers work is by directing cool wind that is circulating at higher levels downwards through vertical openings with oblique sides (also known as directional openings) by leaving only the shaft opposite of the incoming wind open.Nov 3, 2021
What are wind towers used for?
Introduction Wind towers or wind catchers are small towers installed on top of buildings. Wind towers have different shapes and structures. For centuries wind towers have been used for ventilation and cooling of buildings in the hot and arid or humid areas . Wind towers are still used in some areas of Middle East and Egypt ( Fig. 1, Fig. 2).

What is a cylindrical wind tower?
Cylindrical wind towers are the most advanced type of wind towers with better performance than the other three types of wind towers previously described ( Fig. 16 ). Fig. 16. A cylindrical wind tower in Yazd, Iran . Conventional and traditional wind towers have several limitations. Some of these limitations are:.

What is a proposed wind tower?
The proposed wind tower ( Fig. 17) is designed to address the limitations of conventional and traditional wind towers and improve their performance. It is designed to be installed in the maximum wind speed direction of the region. Fig. 17. A view of the proposed wind tower. 2.5. Design of the wind tower’s components .

What is a wind tower made out of?
Carved from layers of recycled cardboard and sheets of aluminium, the six-metre-tall structure was designed as a modern take on the wind towers found in the Arabian Gulf.

Building in Sheffield, England
The Arts Tower is a building at 12 Bolsover Street in Sheffield, England, belonging to the University of Sheffield and which opened in 1965. A spokesperson for English Heritage described it as the most elegant university tower block in Britain of its period. At 78 m (256 ft) tall, it is the second-tallest building in the city, after the 101 m (331 ft) St Paul's Tower on Arundel Gate, which was topped out in 2009. Mitchell Construction a British civil engineering firm, built the Arts Tower. Photographs from their topping out ceremony in October 1964 help to document a different era in UK working conditions.
The Leaning Tower of Pisa
Famous bell tower in Pisa, Italy
The Leaning Tower of Pisa, or simply, the Tower of Pisa, is the campanile, or freestanding bell tower, of Pisa Cathedral. It is known for its nearly four-degree lean, the result of an unstable foundation. The tower is one of three structures in the Pisa's Cathedral Square, which includes the cathedral and Pisa Baptistry.
A tower block
Tall building; as opposed to a low-rise building
A tower block, high-rise, apartment tower, residential tower, apartment block, block of flats, or office tower is a tall building, as opposed to a low-rise building and is defined differently in terms of height depending on the jurisdiction. It is used as a residential, office building, or other functions including hotel, retail, or with multiple purposes combined. Residential high-rise buildings are also known in some varieties of English, such as British English, as tower blocks and may be referred to as MDUs, standing for multi-dwelling units. A very tall high-rise building is referred to as a skyscraper.

Graphic tool used by meteorologists
A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. Historically, wind roses were predecessors of the compass rose, as there was no differentiation between a cardinal direction and the wind which blew from such a direction. Using a polar coordinate system of gridding, the frequency of winds over a time period is plotted by wind direction, with colour bands showing wind speed ranges. The direction of the longest spoke shows the wind direction with the greatest frequency.
