Abstract Nanofluids are of great importance due to the superior performance on improvement of thermal performance. In this work, glycerol (GL) based binary solvent system, including GL/water (W), GL/ethylene glycol (EG), and GL/dimethyl sulfoxide (DMSO) were studied comprehensively regarding their melting points, boiling points, thermal conductivities and viscosities. Graphene oxide (GO), which was prepared through a chemical exfoliation method, was subsequently dispersed into those solvents to make nanofluids. Thermal conductivity and viscosities were studied to evaluate the performance of those nanofluids. It is revealed that a maximum 20% thermal conductivity enhancement of nanofluid is achieved by just filling 0.6 vol% of GO.

甘油基二元溶剂：热性能研究及其在纳米流体中的应用

摘要 纳米流体在提高热性能方面具有优越的性能，因此具有重要的意义。在这项工作中，基于甘油 (GL) 的二元溶剂体系，包括 GL/水 (W)、GL/乙二醇 (EG) 和 GL/二甲基亚砜 (DMSO) 的熔点、沸点、热导率进行了综合研究和粘度。通过化学剥离方法制备的氧化石墨烯 (GO) 随后被分散到这些溶剂中以制备纳米流体。研究了热导率和粘度以评估这些纳米流体的性能。结果表明，仅通过填充 0.6 vol% 的 GO，纳米流体的热导率最高可提高 20%。
