چکیده مقاله :
Despite the spread of science in all fields in today's world, human beings are always seeking new knowledge. Energy is one of the issues that human beings significantly think about its control and protection. Solar chimneys can go through a very valuable process in hot and dry climates by creating air conditioning. Thus, the study of factors affecting the optimization of the solar chimney is inevitable. Since there is airflow in the solar chimney, it can be important to study the number of openings that cause air to enter the building in the wall of the building envelope. In this research was done using the simulated environment method in Design Builder software and the CFD analysis. Thus, a result of 25% was obtained by examining five sample openings with different percentages in the wall, which was the most suitable option for the model in terms of economic and energy efficiencies.
