 The paper discusses the effects of adding three different types of nanoparticles, ferric oxide, zinc, and gold, to a base fluid of blood. The authors focus on the heat transfer properties of this hybrid nanofluid, as it has potential applications in pharmaceuticals. They use a fractional derivative approach to solve the governing equations, and find that the addition of any of these nanoparticles increases the rate of heat transfer compared to the base fluid alone.
