In this work, experimental study was performed to measure the thermophysical properties of water-based nano-emulsion of phase change material (tricosane). The particle size distribution, the dynamic viscosity, the thermal conductivity and the specific heat of the emulsion in the different mass fraction of the phase change material (PCM) over the temperature range of 20–60 °C were measured. Based on the results, the thermophysical properties of the based fluid are strongly affected by the phase change progress of the PCM. Measured results show that the dynamic viscosity of the water-based PCM nano-emulsion in the heating process is lower than that in the cooling process. Besides, the higher the mass fraction of the PCM is, the larger the dynamic viscosity is. In the temperature ranges of 20–40 °C and 40–60 °C, the temperature change on the thermal conductivity is insignificant. However, in the phase change temperature range, the thermal conductivity increases considerably.

在这项工作中，进行了实验研究以测量相变材料（三tric烷）的水基纳米乳液的热物理性质。在20–60°C的温度范围内，测量了相变材料（PCM）不同质量分数下乳液的粒径分布，动态粘度，导热系数和比热。根据结果​​，PCM的相变进程会严重影响基础流体的热物理性质。测量结果表明，水基PCM纳米乳液在加热过程中的动态粘度低于在冷却过程中的动态粘度。此外，PCM的质量分数越高，动态粘度越大。在20–40°C和40–60°C的温度范围内，温度对导热系数的影响很小。但是，在相变温度范围内，热导率显着增加。
