Thermal performance assessment of alumina/graphene oxide hybrid nanofluid in annular passage of multiple configurations

The current study investigated the effect of both the intrinsic and extrinsic parameters of annular flow on the thermal performance of alumina/graphene oxide (Al2O3/GO) for fully developed turbulent flow by A 3-D CFD model. A fully circular annular pipe (the cross-section is a full circle for both t...
