Recent research conducted by Gholamhosein Gholami from the Faculty of Hakim Sabzevari University has shed new light on the ancient windmills of the Sistan region, particularly focusing on Windmill No. 2 in Machi “Ghaleh Cheh Reeis.” This study, published in the journal ‘مسکن و محیط روستا’ (Housing and Rural Environment), aims to analyze the physical elements of these historical structures and their efficiency in harnessing wind energy, a crucial aspect given the region’s notorious 120-day winds.
The Sistan windmills, recognized as some of the oldest in the world, have evolved through centuries of architectural innovation and trial-and-error. Gholami’s research employs a combination of wind tunnel experiments and computer simulations to assess how various structural elements impact the windmills’ performance. “Our findings indicate that the traditional understanding of wind dynamics by Persian architects has been pivotal in enhancing the windmills’ efficiency,” Gholami stated.
The study highlights the importance of the windmill’s superstructure and wind-catching facade, which consists of three distinct parts: a main wind entrance port, a smaller secondary port, and guiding fins. Through meticulous experiments, Gholami discovered that modifications to these components significantly improve the windmills’ ability to convert wind energy into mechanical power. Notably, the upgraded model 2, which incorporated guiding fins, demonstrated a marked reduction in whirlwinds and an increase in wind flow concentration, thereby enhancing the overall efficiency.
The implications of this research extend beyond historical analysis; they offer valuable insights for the construction sector. With a growing emphasis on sustainable energy solutions, understanding the design principles of these ancient windmills could inform modern architectural practices. Gholami emphasized, “By integrating traditional knowledge with contemporary technology, we can develop more efficient and sustainable wind energy systems.”
As the construction industry increasingly seeks innovative ways to harness renewable energy, the findings from Gholami’s research could lead to the development of new windmill designs that are not only functional but also environmentally friendly. The potential for commercial applications is significant, particularly in regions prone to high winds, where traditional designs could be adapted for modern use.
This study not only honors the ingenuity of Persian architects but also paves the way for future developments in sustainable energy architecture. By revisiting and revitalizing ancient designs, the construction sector can find fresh solutions to today’s energy challenges.
