Abstract: The paper examines the effect of the solar chimney's stack height, depth, width and inlet position on the interior performance (air temperature and speed at 1.20 m height above the ground) as well as proposes an optimal tropical solar chimney design. Simulations show that the output air temperature remains constant while the solar chimney's width is the most significant factor influencing output air speed. The solar chimney's inlet position has limited influence on the output air speed although regions near the solar chimney's inlet show an increase in air speed. Furthermore, a regression model is developed based on the solar chimney's stack height, depth and width to predict the interior air speed. To optimize solar chimney in the tropics, the recommendation is to first maximize its width as the interior's width, while allowing its stack height to be the building's height. Lastly, the solar chimney's depth is determined from the regression model by allocating the required interior air speed. © 2013 by the authors; licensee MDPI, Basel, Switzerland.
