Abstract

Latent Heat Thermal Energy Storage (LHTES) is the method to store thermal energy by changing the phase of Phase Change Material (PCM). This method is being developed to store heat loss for increasing energy efficiency. In this paper, the effect of variation flow rate on the melting characteristics PCM was investigated by three-dimensional numerical simulation using ANSYS FLUENT 17. The set-up of this research was carried out on concentrically two cylindrical tubes with diameter outer tube 10 cm and length 60 cm while diameter inner tube 5 cm and length 50 cm. The inner tube is used as a PCM container and the outer tube which has bottom and top hole is used as Heat Transfer Fluid (HTF) circulation. Variation HTF or hot water flowrate was carried out by 4L / min, 8L / min and 12 L / min while the temperature is kept at 75oC, then flowed through bottom hole and out to top hole. From this study it was found that the variation flow rate did not have significant effect on the melting pattern, only the greater flow rate, the smaller melting time. Natural convection is the main role of heat transfer when melting.

数字研究:腹部放电对气瓶蜡融化特性的影响
潜热蓄热是通过相变材料(PCM)的相变来储存热能的一种方法。这种方法被用来储存热损失,以提高能源效率。本文利用ANSYS FLUENT 17进行三维数值模拟,研究了变流量对PCM熔化特性的影响。本研究的设置是在同心的两个圆柱形管上进行的,外管直径10厘米,长60厘米,内管直径5厘米,长50厘米。内管用作PCM容器,外管有底孔和顶孔,用作传热流体循环。在温度保持在75℃的情况下,分别以4L / min、8L / min和12l / min的热水流量变化HTF,从井底流出至井顶。从本研究中发现,流量变化对熔化模式没有显著影响,只是流量越大,熔化时间越短。自然对流是熔化时传热的主要作用。
