“…In addition, it can be seen that the melting temperature of PCM obtained by MD simulation is 288.92 K, which is consistent with the literature data. 71 All the above analysis shows that a good agreement has been observed between the simulation values and literature data. This means that the simulation is reliable and effective.…”

“…0.859 gÁcm −3 , which is consistent with the experimental result of 0.860 gÁcm −3 . 71 In addition, the RE between experiment values and MD simulation values is 0.86%. When the PCM is in the liquid phase, the values of ρ Liquid obtained from Reference 44 are slightly higher than the MD simulation values.…”

“…The MD simulation values of ρ PCM in both solid and liquid phases as well as the error bars are shown in Figure 4, where the experimental results of PCM in literatures 44,71 are also presented in Figure 4. In order to facilitate the comparison, the three-segment linear fitting of the ρ PCM obtained by simulation is carried out in this paper, and the error analysis between the fitting result and the experimental value is also performed.…”

The thermophysical properties of phase change material (PCM) directly affect the performance of underwater vehicles. The accuracy of the phase change transfer model is an important index for evaluating the performance of PCM as well. In this paper, a molecular dynamics approach is proposed to obtain the thermophysical properties of PCM under different pressures. On such a basis, the modified models of "temperature-pressure-density," "temperaturepressure-thermal conductivity" and "pressure-specific heat capacity" are established. By comparing the simulation results with the unmodified phase change transfer model and the laboratory experimental results, it can be seen that the modified phase change transfer model has higher accuracy. Furthermore, an ocean thermal energy conversion system for underwater vehicles is deployed in the South China Sea to test the utilization performance. By the contrast between the simulated calculation of the modified model and the sea trial results, it is found that the root mean square (RMS) of accumulator pressure between the simulation and sea trial is 0.2565, and the energy storage volume RMS is 1.6868. When the accumulator pressure reaches 205 bar, the time error is 0.58%, and the energy storage volume error is 3.16%. The results indicate that the modified model is effective in practical application.

“…And, it was compared with the result of numerical analysis [2]. The direct contact melting of hydrocarbon mixtures of tetradecane and hexadecane binary mixture, and pentadecane and octadecane binary mixture were investigated experimentally [3]. In addition, during the solidification process, direct heat exchanging behavior of a sodium thiosulphate pentahydrate with a heat transfer oil has been investigated [4].…”
