Abstract

Abstract
Problem Statement: The city of Bushehr on the northern coast of the Persian Gulf is one of the most critical hot and humid climates in Iran. Always, natural ventilation has been one of the common methods of providing thermal comfort to residents Taremeh is one of the semi-open spaces effective in natural ventilation. This research is trying to investigate the ventilation in the residential area of Bushehr based on the Taremeh and its parameters.
Research objectives: This research was carried out to investigate the natural ventilation caused by the potential of the Taremeh.
Research method: This study employed a mixed research method including field survey, library research, and document reviews of historical buildings. In the experimental part of the study,the independent variables affecting the quality of natural ventilation were identified and the dependent variables were measured by accurate digital devices in a case study (Dehdashti building) and then its data was used for software validation. After the validation, the models were simulated in Cfd Autodesk 2018 software, relying on the CFD method. velocity and age of air as well as the wind circulation were evaluated.
Conclusion: The results show that the “inner Taremeh “ in a linear form in a state that is a part of the yard area has the highest and the 4-sided Taremeh has the lowest velocity. Wind circulation is less in the middle area and more towards the walls. The internal U-shaped Taremeh has the highest speed in the room. By reducing the number of columns and increasing the dimensions of the columns in the Taremeh, the speed of airflow in the Taremeh space decreases. As the height increases from the ground floor to the first and second floors, the velocity in Taremeh increases in all cases. In the “middle Taremeh “, increasing the width of the Taremeh reduces the velocity to some extent. From the perspective of depth, the depth of 3.5m for the Taremeh has the most optimal ventilation in terms of velocity and the lowest age of air.
