Abstract:
In this article, a numerical study is performed on a Trobme wall in a tropical city for two
seasons, summer and winter. A 1 × 1.5 m Trobme wall with a thickness of 15 cm is designed and
analyzed. A 1-inch-diameter tube filled with PCM is used to enhance efficiency. The wall is analyzed
at different times of the day for the two cold and hot seasons for different sizes of wall holes in the
range of 70 to 17.5 cm when the wall height is 20 cm. A fluid simulation software is employed for
the simulations. The problem variables include different hours of the day in the two cold and hot
seasons, the presence or absence of PCM, as well as the size of the wall hole. The results of this
simulation demonstrate that the maximum outlet temperature of the Trobme wall occurs at 2 P.M.
Using PCM on the wall can allow the wall to operate for longer hours in the afternoon. However, the
use of PCM reduces the outlet wall temperature in the morning. The smaller the size of the wall hole,
the more air can be expelled from the wall.
