Analysis and Comparison of Wind Currents in the Singular Windmills of Sistan and the Simple Windmill of Khorasan by Using the ANSYS Software

The architecture of Iran is full of hidden secrets and serves as the key to meet the needs of people who have wisely converted climatic and geographical weaknesses and threats into the strengths and golden opportunities. This capability has been based on long experiences. Use of windmills is one of the most important of these experiences. A windmill is a structure of desert architecture in Iran. This small and seemingly simple factory represents the integration of architectural art and industrial knowledge of Iranian past generations in the proper use of local and indigenous facilities. Windmills have been built in southern half of Khorasan and Sistan wherever there is good wind. Recognizing the function of these structures along with the depletion of fossil fuels can lead to the use of the knowledge of constructing windmills in modern structures in order to produce energy. With the aim of identifying the functions of these structures, this research reviews the operation of windmills in the two regions of Sistan and Khorasan and seeks to answer the question “which of Khorasan and Sistan windmills represents better operation in using the wind energy?” For this purpose, the ANSYS software, version 19, has been used to compare the functions of these two wind-operated structures. The results of the research indicate that Sistan windmill has better operation due to its wider span and more pleasant air entrance.
