摘要

为研究方腔式蓄热单元内有机相变材料融化过程的传热规律

数值模拟了不同体积分数石墨烯纳米片填充下复合相变材料融化过程的液相分数和努塞尔数的变化; 针对方腔蓄热单元热量在顶端聚集的问题

构建了分层模型

模拟了不同模型中复合相变材料的融化过程。结果表明:当石墨烯纳米片体积分数分别为1%、3%和5%时

复合相变材料完全融化时间分别为32.1、20.0、17.5 min

与纯质石蜡相比

融化时间分别缩短了70.47%、81.62%和83.92%; 方腔上下等分时

融化时间相比于未分层时缩短11.88%; 将方腔上下部分别填充体积分数1%与5%的复合相变材料

相比于未分为层时

整体填充3%的复合相变模型融化时间缩短了25.83%。由模拟结果可得

在石蜡中添加石墨烯纳米片可以使其导热性能有很大程度的提高

同时黏度增长程度较小

对自然对流产生的影响也比较小。综合考虑可以发现

在石蜡中添加石墨烯纳米片可以强化其传热性能; 分层模型可以缩短相变材料融化时间

合适的填充方案能够进一步加快矩形方腔的融化过程。

Abstract

In order to research the heat transfer problem of organic phase change materials melting in the square cavity heat storage unit

liquid fraction and mean Nusselt number of composite phase change materials under different filling rates during melting are analyzed. To solve the problem of heat accumulation at the top of the square cavity unit

the layered model is constructed to simulate the melting process of the composite phase change materials in different models The results show that when the contents of graphene nanosheets are 1%

3% and 5%

the complete melting times of the nanoparticle-enhanced phase change material are 32.1

20.0 and 17.5 min

respectively

which are 70.47%

81.62% and 83.92% shorter than those of pure paraffin. When the square cavity is equally divided at the top and bottom

the melting time is reduced by 11.88% compared to the unlayered one. When the upper and lower parts of the square cavity are filled with 1% and 5% volume fraction of the composite phase change materials respectively

the melting time of the composite phase change model with an overall filling of 3% is reduced by 25.83% compared to that when it is not divided into layers. From the simulation results

it can be concluded that the addition of graphene nanosheets to paraffin wax can lead to a large degree of improvement in its thermal conductivity

as well as a smaller degree of viscosity growth and a smaller effect on natural convection. When considered together

it can be found that the addition of graphene nanosheets to paraffin can strengthen its heat transfer performance; the layered model can shorten the melting time of the phase change materials

and a suitable filling scheme can further accelerate the melting process of the rectangular cavity.
