A novel phase change material containing mesoporous silica nanoparticles for thermal storage: A study on thermal conductivity and viscosity

Enhanced thermal conductivity of n-octadecane containing carbon-based nanomaterials

“…Recently, there has been a considerable interest to enhance the thermal conductivity of organic PCMs by addition of small amount of nanostructured materials [12][13][14][15][16]. Among these materials, carbon-based nanomaterials have been received more attention because of their anomalous thermal conductivity (~3000 W/m K) with respect to poor conductance of organic PCMs (~0.2 W/m K).…”

Experimental investigation of phase change material melting in rectangular enclosures with horizontal partial fins

“…Various methods for heat transfer enhancement of PCMs have been proposed and studied by many researchers. Some of the most common methods include using extended surfaces [12][13][14][15][16][17], impregnation of porous materials [18][19][20][21], placement of high thermal conductivity metal structures [22,23], embedding heat pipes [24,25], dispersing high conductivity particles [26][27][28], adding carbon fibers [29,30] and carbon nanotubes [31,32]. Dispersing high thermal conductivity materials into PCMs seems to be less practical compared with incorporating metal structures into PCMs since the dispersed material usually agglomerates and sediments to the bottom of the enclosure in long-term operation [33].…”

Research on Measurement Technology of Thermophysical Properties for Full-Scale Phase Change Material Product in a Container

“…Then, the areal enthalpy of the specimen (h As (T a ,T b )) can be calculated in Equation (9), which contains the areal enthalpy of the container and the PCM. In addition, the volume specific heat within each temperature step is considered to be linear, so the volume specific heat of the specimen with the container at the average temperature (Equation (10)) is obtained, which is shown in Equation (11).…”

“…For the measurement of thermal conductivity for a solid PCM, the hot wire method [6][7][8], the HotDisk method [9][10][11], and the steady state method [12][13][14] are widely used. In addition, the steady state method, including the heat flow method analysis (HFMA) method, is generally used to measure the thermal conductivity of a full-scale product.…”
