MATHEMATICAL STUDY OF HEAT TRANSFER IN A STAGNATION FLOW OF A HYBRID NANOFLUID OVER A STRETCHING/SHRINKING CYLINDER

The steady two-dimensional incompressible boundary-layer, stagnation-point flows of an ordinary nanofluid and a hybrid CuO + MgO nanofluid over a stretching/shrinking cylinder were investigated using the dimensionless master Prandtl equations. It was established that the thermal conductivity of the hybrid nanofluid is higher, it transfers a larger amount of heat from the curved surface of the cylinder, and the skin friction force acting on its flow is larger, as compared to those of the ordinary nanofluid, and that the skin friction force acting on the flows of these fluids increases with increase in the volume fraction of nanoparticles in them.
