Confinement Effect of Graphene Interface on Phase Transition of n-Eicosane: Molecular Dynamics Simulations
Published in Langmuir, 2020
In this article, the phase transition behavior of n-eicosane in slit-shaped pores between sheets of graphene is investigated by molecular dynamics simulation. It is found that the graphene interface makes the phase transition temperature of n-eicosane increase, under the initial slit widths of 1.5–5.3 nm.

A new structure of PCHE with embedded PCM for attenuating temperature fluctuations and its performance analysis
Published in Energy, 2022
To attenuate the temperature fluctuations in the cycle, this study proposes a new structure with phase change materials embedded in the printed circuit heat exchanger. This structure package can contain a variety of phase change materials in a stepwise arrangement and a composite phase change material with expanded graphene. The effects of different flow directions, the number of layers in the phase change material ladder, whether the phase change material is compounded with expanded graphene or not, and the thickness of the phase change material were numerically compared.

Effect of pressure on regenerative cooling process of endothermic hydrocarbon fuel at severe pyrolysis conditions
Published in Aerospace Science and Technology, 2023
In order to fill the gap in existing research on the pressure effects at severe pyrolysis, the influence of pressure on the flow field, pyrolysis behaviours, heat transfer, and surface coking are numerically investigated in this study. The results indicate that the velocity-temperature curves at different pressures have two intersections due to the difference in initial pyrolysis temperature, reaction rate, and product distribution.
