主要从理论数值模拟和近场辐射实验研究的角度介绍了近几年在近场热辐射传热方面的最新研究成果。理论研究的焦点主要集中在石墨烯复合材料、人工加工或合成超材料等方面的传热研究。实验研究的焦点是实验室基于纳米尺度近场热辐射测量的设备制造与方法创新。目前实验上已经实现了最小距离仅为2 nm的极近场热辐射测量。近场热辐射的进一步研究可为热光伏、辐射制冷以及高效能源收集应用提供理论基础。

From the perspective of theoretical numerical simulation and near-field radiation experimental research, the latest research results in near-field thermal radiation heat transfer are introduced. The focus of theoretical research is mainly on heat transfer studies in graphene composites, artificial processing and synthetic metamaterials. The focus of experimental research is on laboratory equipment manufacturing and method innovation based on nanoscale near-field thermal radiation measurements. Very near-field thermal radiation measurements with a minimum distance of only 2 nm have been experimentally implemented. Further research on near-field thermal radiation provides a theoretical basis for thermal photovoltaic, radiant cooling and efficient energy harvesting applications.
