Kerosene graphene nanoplatelets (GNP) nanofluids have a potential use in regenerative cooling of semi-cryogenic rocket thrust chamber. Before they can be used, more must be known about this substance's physical qualities. This study focuses on finding the effective thermal conductivity of this type of nanofluid, specifically at .005, 0.05 and 0.2 weight percentage (wt%) and 300, 500 and 750 mm2/g, specific surface area (SSA) of GNP. ...
