摘要

将石墨烯纳米片 (GNP) 添加到纯相变材料中是提高储能系统性能的一种很有前景的方法，其应用需要全面了解石墨烯纳米流体的凝固行为。在本研究中，数值分析了石墨烯质量浓度、腔体尺寸和形状对固液界面演化、温度分布、流线以及凝固速率的影响。采用焓-孔隙率技术跟踪固液界面。结果表明，石墨烯纳米片对凝固的促进作用主要体现在以热传导为主的最后阶段；早期凝固发生在型腔底部，固液界面与型腔本身形状相似，中期和末期分别趋于圆形；在石墨烯质量浓度为1.2 wt%时，凝固时间缩短度达到30.1%；减小腔体尺寸和采用三角形腔体有利于促进相变传热，但会抑制石墨烯对相变传热的增强作用。

Abstract

Addition of graphene nanoplatelet (GNP) into water is a promising method for improving cold storage system performance, and its application requires comprehensive understanding of solidification behavior of GNP-water nanofluid. In the present study, the influences of GNP mass concentration, cold storage cavity size and shape on solid-liquid interface evolution, temperature distribution, streamline profile as well as solidification rate are numerically analyzed. The enthalpy-porosity technique is adopted to track solid-liquid interface. The results show that the enhancement effect of GNPs on solidification is mainly reflected in the final stage in which heat conduction is predominant; the solidification occurs at the bottom of cavity in the early stage, and the solid-liquid interface is similar to the shape of cavity itself and then tends to be circular in the middle and final stages respectively; the reduction degree of solidification time reaches 30.1% at GNP mass concentration of 1.2 wt% under present simulation conditions; decreasing cavity size and adopting triangular cavity are beneficial for promoting the solidification, but they will suppress the enhancement effect of GNPs on solidification.

Key words： cavity shape; graphene; nanofluid; phase change material; solidification
