“…New Trombe wall configurations incorporating PCMs have been developed in recent years to boost their performance [38][39][40][41]. The PCM layer is usually placed on the wall surface but can also be located inside the wall [42]. The use of PCMs in the Trombe wall reduces the annual energy consumption by 10-30%, depending on the climatic conditions [43,44].…”

Latent heat thermal energy storage systems incorporate phase change materials (PCMs) as storage materials. The high energy density of PCMs, their ability to store at nearly constant temperature, and the diversity of available materials make latent heat storage systems particularly competitive technologies for reducing energy consumption in buildings. This work reviews recent experimental and numerical studies on the integration of PCMs in building envelopes for passive energy storage. The results of the different studies show that the use of PCMs can reduce the peak temperature and smooth the thermal load. The integration of PCMs can be done on the entire building envelope (walls, roofs, windows). Despite many advances, some aspects remain to be studied, notably the long-term stability of buildings incorporating PCMs, the issues of moisture and mass transfer, and the consideration of the actual use of the building. Based on this review, we have identified possible contributions to improve the efficiency of passive systems incorporating PCMs. Thus, fatty acids and their eutectic mixtures, combined with natural insulators, such as vegetable fibers, were chosen to make shape-stabilized PCMs composites. These composites can be integrated in buildings as a passive thermal energy storage material.

Sustainable architecture and green building are recognized techniques to address the energy and environmental crises. In this regard, the Trombe Wall has also attracted attention for its potential ability to address the energy and environmental crises. Trombe Wall is regarded as a sustainable architectural technology for insulation. This article reviews the classification and configuration of Trombe Wall and the most relevant content of Trombe Wall research carried out in various countries over the past few decades. This review discusses the characteristics of the main subspecies of the Trombe Wall. In terms of content, according to the research methods of different types of Trombe walls, they can be divided into two categories: theoretical simulation research and experimental research. The advantages of this sustainable architectural technology have been highlighted, and future research questions have been identified.

“…The significance to investigate the Pr > 1 fluids for the scenario considered in this study is due to their numerous occurrences in nature and in practical applications. The most notable example is on the water thermal storage Trombe wall in a solar house where the absorbed sinusoidal solar radiation heats the water, which is of Pr

~ 7.5

) on the sidearm of a reservoir or ocean which is also caused by the absorbed sinusoidal solar radiation 40,41 .…”

The understanding of the transient behavior of the natural convection boundary layer on a heated vertical solid surface is crucial for numerous applications. In this study, scaling analysis is performed to derive the scaling laws for the major parameters that characterize the transient behavior of natural convection boundary layer of a Prandtl number larger than 1 fluid on a vertical solid surface subject to a sinusoidal heating flux in a linearly stratified ambient. It is found that the developed scaling laws are in good agreement with the direct numerical simulation results over wide ranges of Prandtl number, stratification parameter, and frequency of the sinusoidal heat flux.
