| description | BackgroundThe thermal conductivity of graphene nanoparticles doped into the lead bismuth reactor coolant can significantly improve the coefficient of thermal conductivity and specific heat capacity. That will improve the core power of lead and bismuth pile density, reduce the amount of coolant, and ultimately achieve the goal of reducing the reactor volume. It is of great significance for the engineering application of lead bismuth reactor in remote areas and offshore seas.PurposeThis study aims to investigate the thermophysical properties of lead-bismuth-based graphene nanofluids.MethodsFirst of all, different thermal conductivity, viscosity, specific heat capacity and other prediction models were employed to study the thermophysical properties of metal-base Graphene nanofluids. The strengthening mechanism of nanofluids was analyzed, then a hermophysical calculation model suitable for lead-bismuth-based graphene nanofluids was put forward.ResultsThe results show that the coefficient of thermal conductivity, specific heat capacity and viscosity of lead bismuth matrix with graphene nanoparticles are significantly improved, and the thermal conductivity, specific heat and viscosity increase significantly with the increase of the concentration when the suspension is relatively stable. When the concentration reaches 20%, the thermal conductivity of mickey fluid can be increased by 80%. However, the viscosity is increased by about 100% simultanously.ConclusionsThe influence on thermophysical property should be considered while increasing the concentration of graphene nanofluids. |
