Graphene specific heat

WebThe specific heat increases rapidly with temperature, up to 1500K where it levels off at approximately 2.2 kj/kg.K as shown in Fig.3.8. It is believed to be relatively insensitive to the differences between the various grades of synthetic graphite, and the spread of values found in the literature may be attributed to experimental variations. WebA prediction model for the thermal conductivity, viscosity, and specific heat capacity of a graphene-based nanofluid is established, laying a theoretical foundation for the subsequent application of lead–bismuth-based graphene nanofluids as the cooling medium in lead–bismuth cooled reactors.
