Abstract

One of the most important problems of office buildings in hot and humid cities like Ahvaz is the lack of effective ventilation of closed corridor spaces. Due to the low traffic and the reduction of energy costs, the use of air conditioning systems in these corridors is not of much concern to their owners. The main goal of this research is to improve the ventilation quality in the corridor spaces of Ahvaz office buildings, which is possible through modifying the architectural elements and position of blowers and suckers. The current research is a kind of interdisciplinary research method: it is a hybrid and innovative method and involves the strategies of experimental research, simulation and case study. In this way, first an experimental study was conducted on the statistical population of the research (corridor spaces of Ahvaz office buildings) and after selecting case study, observations and periodical experimental tests were occured, interventions in architecture and research variables were carried out with the simulation method. In this research, CFD method was used to perform simulations and analysis, and Gambit preprocessor and Fluent software were used (after proving validity and reliability). The results showed that the use of ceiling fans and the change in the dimensions and shape of the corridors, according to the results of this research and the prediction of the back-to-the-wind suction, effectively improved the indoor air flow pattern and by reducing the age of stagnant air and establishing a constant air flow, Provides effective ventilation.
