“…Solar chimneys with different absorber plates, such as 10 PPI or 40 PPI, are utilized in the experiment to compare the data obtained from the two identical solar chimneys. [23] showed it is common for mountain houses to be constrained by the landscape. In the mountainous region of Taihang, a passive solar building design strategy is proposed that takes advantage of the building's location next to a mountain's shady courtyard to act as a cold source for the surrounding outdoor environment.…”

An experimental study has been carried out for testing the thermal performance and the thermal behavior enhancement of solar chimneys that can be achieved by adding metal foam. The solar chimney with test room system was located in Baghdad, Iraq, at latitude 33.3? N, longitude 44.4? E. In the experimental part of this study, outdoor tests were conducted from May to July (2021). On clear days, the tests were conducted from 9:00 am to 4:00 pm. The experimental side will compare the performance of two types of copper metal foam (10 and 40) pores per inch (PPI) heat absorber plates at three different heights (5, 15, and 25 cm). The results showed that the metal foam reduced the average temperature of the absorber plate. The highest temperature reduction was achieved with (10 and 40) PPI absorber plates (13.5 and 8.3)?C respectively at (H= 5 cm) and (60?). The maximum increase in airflow velocity at the solar chimney with (10 and 40) PPI absorber plates is (43.7%) and (25%), respectively, at (H= 5 cm). The absorber plate heights decrease the air velocity at the solar chimney. The reduction in air velocity from (5 to 25) cm for 10 PPI absorber plate to (48.8%). With metal foam as an absorber plate (10 and 40) PPI, the chimney's thermal efficiency is increased. At the absorber plate's height, the solar chimney's maximum thermal efficiency was 49, 66.2, and 72.1 percent (5 cm). At the height of the absorber plate, the maximum air change per hour was 18.8, 24.4, and 27.21 (5 cm).
