The place of fluid engineering in the tallest brick dome in the world (Soltanieh dome)

The most significant work of Iranian civilization in the Islamic era, as the tallest brick dome in the world, is 700 years old, which shows its greatness and stability in the vast plain of windy weather with harsh climate. The secret of the stability of this building among the air currents resulting from the geography of the region is undoubtedly the use of fully engineered structures based on aerodynamics in its architecture, which is used today for the endurance and stability of buildings in civil structures. The present study has based on the damages and erosions caused by air currents and climatic conditions on the Soltanieh building. The research method used in this article is descriptive-analytical with laboratory and library studies. The method and tools used are review of written documents, field and laboratory studies. The results indicate that the selection of nested porches on the upper floor of the building in an octagonal design in the direction of the prevailing wind in the area and the presence of a window on each side of the porch is designed based on climate, air resistance and its effects. Research objectives• The position of fluid engineering in the tallest brick dome in the world (Soltanieh dome)• Familiarity with.Research questions• What is the position of fluid engineering in the tallest brick dome in the world (Soltanieh dome)?• What is the familiarity with the appearance of the building and the considerations of the effect of atmospheric currents on it?
