Bahrani H, Ranjbar E, Ahmadi S. An Analysis of the Function of External Senasir Types and Their Effects on the Wind Flow in the Historical Part of Bushehr. Naqshejahan 2018; 8 (3) :179-186

Bushehr has a valuable historical texture that is a very rich example of a coherent design with a climate from the macro level location to elements and architectural details. Based on the climatic challenges in the contemporary world, revising samples such as Bushehr can provide a basis for creativity in urban design and contemporary architecture. Given the ever-increasing advances in climate analysis, there is a need for a new insight into the analysis of urban spaces and architecture in the historical context of Bushehr. Senasir is one of the important elements in the climatic function, landscape and identity of the historical context of Bushehr. Most of the previous studies have considered this important element of Bushehr urban architecture from the sight of descriptive researches. The purpose of this paper is Senasir identifying and parametric analyzing to clarify its existential cause in terms of quantitative analysis. In this research, after studying the previous studies based on the content analysis method, the Senasir influence on the flow of winds based on Computational Fluid Dynamics (CFD) in Fluent and Gambit softwares has been investigated.
Senasirs have a significant impact on wind speed and direction change. It introduces Senasir as a thermal comfort producer space in the historical context of Bushehr and its specific climatic conditions, especially in the warmer seasons. The result of this study in the accurate identification of the Senasir’s function can be the basis for design creativities tailored to the wind flow in cities in Iran.
