The composite preparation of phase changes materials There are several methods to successfully integrate phase change materials with materials of the building envelope and bring them into practice. (1) Impregnation is a method that involves submerging porous material in molten materials with phase change. The method uses capillary action and encapsulates phase change substances. This process is easy to follow, it’s simple and you can prepare phase change building materials with ordinary materials any time and anywhere. It will prevent the phase change material from flowing because it can reach the level of the liquid phase changing material’s top tension. Gypsum board works well with various phase change material, including methyl esters, short chain fat acids and SUNIC acids. (2) The Direct-Addition method: It involves the addition of phase changes materials directly to the building material preparation. These advantages include a quick process, low cost, and uniform distribution. Feldman et al. Feldman et.al. Research has shown that phase switch gypsum board is capable of significantly reducing indoor temperature fluctuations. (3) Packaging method The two main types of packaging are micro package and macro package. It is used to store phase change material in small containers (e.g., pipes, bags or boards). Microencapsulation is the process of encapsulating phase change materials (PCMs), into polymer films. Both materials and their components are compatible. Although this technique is more efficient than others, its heat transfer area can be large. Therefore, heat transfer may not be as strong. One type of composite material which is prepared via encapsulation, the shape-stabilized phases change material (or SSPCM), has also been popular in recent years. It is made of phase material (core materials), polymer material (polymer material), and encapsulation and capsule material (capsule materials). It has a high melting temperature and plays an essential role in the formation of a spatial structure. The capsules encapsulate it. The composite material itself has some strength but is very difficult to leak. Its stored energie can compare to those of normal phase change materials. Numerical simulations of heat transport in phase change material ANSYS remains the standard software used for phase transformation analysis. American finite element manufacturer, ANSYS developed it. The program is general finite-element software that has functions for fluid, structure and magnetic field. Because phase transition involves latent heat absorption/release, it’s a non-linear thermoanalysis problem. ANSYS analyzes phase transformation, which is one of the main functions. ANSYS analyzes latent heating of materials and defines enthalpy (product density, specific heat, and integration of heat) which simplifies calculation. Sun Xiao (and others) used Ansys’ powerful non-linear analyze function to simulate temperatures in a composite phase switch wall made of paraffin & gypsum. The ribbed structure aids in latent heat preservation of phase changes materials. Chai Guiorong created a mathematical model based ANSYS software. It calculates and analyzes the heat transfer characteristics, as well energy saving effects of phase changing walls that are made from concrete different in thickness or phase change materials different in thickness. According to the calculations, one can increase the energy efficiency of a concrete wall with varying thicknesses by increasing its shape-stabilized layer. This is because the wall’s surface temperature will fluctuate linearly when the material thickness decreases. Conclusion Though the research into phase-changing materials has progressed in theory, many types of phase material are not suitable for all engineering fields. Future research is focused on the development of phase change material suitable for different situations. Additionally, traditional techniques and processes remain in place for the preparation of phase changes materials. Microcapsules are a promising encapsulation method that has recently been proposed by researchers. It is difficult to know how to integrate phase changes into matrix materials. This remains the subject of much research. As computer technology advances rapidly, researchers increasingly use it to simulate phase change issues. Furthermore, the validity of the simulation results is well documented, making this a more practical tool for Phase Change Materials Research. You can build a more exact mathematical model by looking at the whole picture. Future generations will find the general law useful. Additionally, software tools for phase changes analysis are rare, which makes it crucial to design software programs that perform better.
