Visualized-experimental investigation on the energy storage performance of PCM infiltrated in the metal foam with varying pore densities

Visualized-experimental investigation on the melting performance of PCM in 3D printed metal foam

“…However, the PCM close to the bottom absorbs the heat from both bottom metal and the plexiglass, and it melts faster than that at the top. Appling similar PPI and porosity composite PCM made by conventional methods, Li et al [3] observed similar melting processes and heat transfer performance.…”

“…In order to quantitatively compare the thermal performance, the energy storage power was introduced [35] and defined as the ratio of the heat storage capacity to the complete melting time.…”

“…To overcome this limitation, great effort has been devoted to improving the thermal conductivity of PCM. In general, two typical methods are normally used to improve the thermal conductivity of PCM, they are: (1) complexity of PCM with solid media, such as fins [1][2] or metal foam [3][4]. (2) enhancement with nanoparticles [5][6], or carbon fibers [7][8] dispersed into the PCM.…”

“…(2) enhancement with nanoparticles [5][6], or carbon fibers [7][8] dispersed into the PCM. According to [1][2][3][4][5][6][7][8], the metal foam has distinctive characteristics of high thermal conductivity, large specific surface area, strong structural interconnection and a good fluid mixing effect, which could be used as a good candidate for improving the performance of PCM [9].…”

Design and assessments on a hybrid pin fin-metal foam structure towards enhancing melting heat transfer: An experimental study

“…Besides, they also optimized the porosity distribution and obtained another 28% improvement compared with the uniform foam. Li et al [33] built a test bench to examine the melting procedure of PCM with copper foam. A series of experimental observations are made under different foam parameters.…”
