Abstract

This study considers the potential of application of graphene-based nanofluids as heat-transfer agents in direct absorption solar collectors. It has been revealed that graphene-based nanofluids have superior absorption ability when interacting with monochromatic (520 nm) and near-IR radiation. As compared with distilled water, the use of graphene-based nanofluids as working fluids in direct absorption solar collectors increases their efficiency even at very low concentrations of dispersed phase particles. However, in order to apply graphene-based nanofluids as working fluids in energy systems, some issues need to be solved, primarily those related to their low stability and thermal instability.

石墨烯基纳米流体作为直接吸收太阳能集热器热载体的研究进展

本研究考虑了石墨烯基纳米流体作为传热剂在直接吸收式太阳能集热器中的应用潜力。研究表明，石墨烯基纳米流体对单色（520 nm）和近红外辐射具有较好的吸收能力。与蒸馏水相比，使用石墨烯基纳米流体作为直接吸收太阳能集热器的工作流体，即使在分散相颗粒浓度非常低的情况下，也能提高其效率。然而，为了将石墨烯基纳米流体作为工作流体应用于能源系统，需要解决一些问题，主要是与其低稳定性和热不稳定性有关的问题。

期刊介绍： Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
