Abstract :

Wind towers are historical Iranian vernacular architectural innovation and traditional wind towers are structured as static cooling ventilation system. The process is performed by using of renewable energy of wind. In this research, wind towers are studied in the context of vernacular architecture of hot dry climates of Iran and the city of Yazd in arid is selected. The different architectural forms of wind-towers have been seen in Yazd. This article indicates the fact that formal characteristics have played a major role in their functions. From the architecture point of view, learning about wind catchers of Yazd city in this study is done by the means of the field surveys. Research method for selection of the case is randomly chosen and based on explanation and analytical method. Wind catcher typology and knowledge of the relationship governing the wind catchers architecture were those measures that are taken for the first time. The typology of the wind-catchers is done by the physical analyzing, patterns and common concepts as incorporated in the wind catchers. How the architecture of wind catcher can influence their operations or performances by analyzing thermal behavior are the archetypes of selected wind catchers. This study has used calculating fluids dynamics science, fluent software and numerical analysis as the most accurate analytical approach. 3 types were stimulated in soft ware and results show that they are different to each other and one of them has more improved operation.
