Thermo-mechanical analysis of copper-encapsulated NaNO3–KNO3

Encapsulated Nitrates Phase Change Material Selection for Use as Thermal Storage and Heat Transfer Materials at High Temperature in Concentrated Solar Power Plants

“…According to Lopez et al [32] shell cracking during heating processes could be also avoided by reducing the pore-wall rigidity, increasing pore-walls thickness or increasing pores' connectivity. According to Parrado et al [37] pressure decreases with time, guaranteeing that the shell will not crack, during cooling process.…”

Integration of environmental indicators in the optimization of industrial energy management using phase change materials

“…By properly selecting the PCM, this technology can be used in the temperature range of 300-400°C [12]. NaNO 3 is a typical inorganic salt example used in the mentioned above temperature range [13] and even a combination of a deformable copper shell filled with a nitrate mix of KNO 3 -NaNO 3 can be used as example of encapsulated PCM [14]. Although required materials for encapsulation (refractory steel, extruded ceramics) are recognised to be expensive [15], their long lifetime upon charging-discharging cycles reduces the financial impact.…”

Thermal stress analysis of PCM containers for temperature smoothing of waste gas

“…Some examples available in literature analyse expansion of PCM in liquid phase usually in spherical containers [7,8] and rarely in cylindrical container [9]. This work then aims to propose a simplified methodology for the thermo-mechanical analysis of a PCM system when in solid state, which would also allow identifying the most relevant design parameters for subsequent experimental validation.…”
