Thermal behavior of water base-fluid in the presence of graphene nanosheets and carbon nanotubes: A molecular dynamics simulation

This study was examined the thermal behavior of graphene nanosheets/carbon nanotubes-water nanofluid using the molecular dynamics method. First, the atomic stability in simulated structures was investigated by examining kinetic and potential energies. The results of this part represent the convergen...
