Influence of Thermophysical Properties on Magnetite Water-Based Ferrofluid Heat Transfer at Sphere Surface under Magnetic Field and Thermal Radiation

This theoretical study investigated the effect of thermophysical properties on Nusselt number when the magnetic field and thermal radiation are exposed to the ferrofluid flow at the lower stagnation point of a hot sphere surface. The thermophysical properties are important mechanisms considered in t...
