Heat Transfer Enhancement of Modified Sodium Acetate Trihydrate Composite Phase Change Material with Metal Foams
In this paper, an experimental study is performed to enhance the heat transfer ability of phase change material (PCM) using copper foam (CF). A numerical model is established to predict the melting and solidification process of composite phase change materials (CPCM) in metal foams. The step-cooling curve of CF/CPCM is ideal, with low subcooling and high thermal conductivity because of its interconnected porous structure and high thermal conductivity. the CF/CPCM physical parameters are in line with the expected target. Therefore, a more suitable solution should be selected for practical applications. The CF/CPCM heat storage and exothermic device basically completes the exothermic solidification process at 3600s, and basically completes the heat absorption and melting process at 4200s, which has a more obvious effect on the overall heat transfer strengthening of the device and reducing the non-uniformity of the material, and the design and construction of the CF/CPCM heat storage and exothermic device can be carried out when the application cost is possible.
期刊介绍:
The Journal of Porous Media publishes original full-length research articles (and technical notes) in a wide variety of areas related to porous media studies, such as mathematical modeling, numerical and experimental techniques, industrial and environmental heat and mass transfer, conduction, convection, radiation, particle transport and capillary effects, reactive flows, deformable porous media, biomedical applications, and mechanics of the porous substrate. Emphasis will be given to manuscripts that present novel findings pertinent to these areas. The journal will also consider publication of state-of-the-art reviews. Manuscripts applying known methods to previously solved problems or providing results in the absence of scientific motivation or application will not be accepted. Submitted articles should contribute to the understanding of specific scientific problems or to solution techniques that are useful in applications. Papers that link theory with computational practice to provide insight into the processes are welcome.
