“…Sonawane et al [50] investigated specific heat of Al 2 O 3 /ATF and reported the anomalous behavior of specific heat with volume concentration. Increase in specific heat capacity has been reported in experimental observations [48,[51][52][53][54][55][56][57]. Pakdaman et al [58] observed 21-42% decrease in specific heat capacity of MWCNT/water nanofluid for 0.1-0.4% vol.…”

“…As of now, the result of experimental data do not signal a discreet and clear cut indication whether there is only decrement in the heat capacity with increment of volume concentration, as has been reported by several investigators. Experimental observations on various nanofluids which show increase of specific heat capacity [48,50,51,[54][55][56][57]59], whereas experimental observations exhibit decrease in specific heat capacity performed by many researchers [18,46,47,50,[60][61][62][63][64][65][66][67][68]. It requires further study to correlate anomalous behavior in variation of specific heats and science behind it.…”

“…Chieruzzi et al enhanced the specific heat of a binary nitrate (NaNO 3 -KNO 3 ) by dispersing various nanoparticles (Al 2 O 3 , SiO 2 , TiO 2 , and SiO 2 -Al 2 O 3 ) [23,24]. The enhanced specific heat of the molten salt nanofluids was explained in various ways, e.g., electron microscope images and molecular dynamics simulation [25][26][27][28][29][30]. Furthermore, a fundamental experimental study into thermal property variations of carbonate salt mixtures was performed using a differential scanning calorimeter (DSC) [31].…”

An anomalous increase of the specific heat was experimentally observed in molten salt nanofluids using a differential scanning calorimeter. Binary carbonate molten salt mixtures were used as a base fluid, and the base salts were doped with graphite nanoparticles. Specific heat measurements of the nanofluids were performed to examine the effects of the composition of two salts consisting of the base fluid. In addition, the effect of the nanoparticle concentration was investigated as the concentration of the graphite nanoparticles was varied from 0.025 to 1.0 wt %. Moreover, the dispersion homogeneity of the nanoparticles was explored by increasing amount of surfactant in the synthesis process of the molten salt nanofluids. The results showed that the specific heat of the nanofluid was enhanced by more than 30% in the liquid phase and by more than 36% in the solid phase at a nanoparticle concentration of 1 wt %. It was also observed that the concentration and the dispersion homogeneity of nanoparticles favorably affected the specific heat enhancement of the molten salt nanofluids. The dispersion status of graphite nanoparticles into the salt mixtures was visualized via scanning electron microscopy. The experimental results were explained according to the nanoparticle-induced compressed liquid layer structure of the molten salts.

“…In NEMD, a constant temperature difference or a heat flux is applied on the computational domain to simulate a heat source and sink. The thermal energy transport between these regions gives a direct indication of the thermal properties of the nano-systems (Feng et al 2015;Mohebbi 2012;Mortazavi et al 2012;Salaway and Zhigilei 2014).…”

Multifunctional nanocomposite materials have been used extensively in aerospace, mechanical, civil engineering industries, and other engineering applications. This is mainly due to the enhanced mechanical characteristics such as high strength-to-weight ratio and the unique thermal and physiochemical properties of these nanostructures. It has been reported that there are significant improvements in the thermal conductivity of composite structures with the addition of low volume fractions of graphene. To understand and develop efficient composite systems with desired thermal characteristics, it is necessary to develop accurate thermal transport models of these advanced composite systems. In this chapter, the authors discuss some of the recent developments in multiscale modeling of the thermal and mechanical properties of advanced nanocomposite systems. To enhance the theoretical model development discussed in this chapter, the authors have also included some relevant works from the literature.
