This paper discusses numerically the thermal behavior of phase change material PCM filled between two walls using CFD code. The novel building wall’s role was to receive and store the solar energy during the day. Then, it release it indoors at night. These CFD simulations aim to compare the liquid fraction and the temperature contours of the proposed double partition walls, which were filled with and without PCM layer in the building under the same temperature and external solar radiation conditions of Tatouine, Tunisia. The findings show the ability of the PCM RT28 to delay the thermal propagation from the outside to the indoors during all the day.

摘要

This paper discusses numerically the thermal behavior of phase change material PCM filled between two walls using CFD code. The novel building wall’s role was to receive and store the solar energy during the day. Then, it release it indoors at night. These CFD simulations aim to compare the liquid fraction and the temperature contours of the proposed double partition walls, which were filled with and without PCM layer in the building under the same temperature and external solar radiation conditions of Tatouine, Tunisia. The findings show the ability of the PCM RT28 to delay the thermal propagation from the outside to the indoors during all the day.
