低维碳纳米流体热物性实验研究
Experimental study on thermophysical properties of low-dimensional carbon nanofluids
摘要
Abstract
Three kinds of low-dimensional carbon nanofluids,carbon dots,carbon nanotubes and graphene nanosheets nanofluids with different mass concentrations,were fabricated by the blending method and observed by the scanning electron microscope(SEM).The thermal properties of the nanofluid and the interfacial thermal resistances between the sensing layers were measured using the continuous-wave frequency-domain thermal reflection(CW-FDTR)experimental method,employing a bidirectional thermal conduction model.The results show that the thermal conductivity of the carbon nanofluid increases with the increase of mass concentration,and the thermal conductivity of the multiwalled carbon nanotube nanofluid is the lar-gest.The interfacial thermal resistance between the sensing layer and the carbon nanofluid both decrease with mass concen-tration increasing,and the interfacial thermal resistance between the sensing layer and the carbon nanotube nanofluid is the smallest.The experimental results of thermal conductivity for three types of nanofluids are in agreement with the predictions based on the Maxwell model.The prepared nanofluids have good dispersion and stability.关键词
