Hybrid nanofluids are new and most fascinating types of fluids that involve superior thermal characteristics. These exhibit better heat-transfer performance as equated to conventional fluids. Our concern, in this paper, is numerically interpret the kerosene oil-based hybrid comprising dissimilar nanoparticles like silver (Ag) manganese zinc ferrite (MnZnFe 2 O 4 ). A numerical algorithm, which ...

Editorial Nanofluids, or fluid suspensions of nanometer-sized structures, are research challenges of rare potential but daunting difficulty. The potential comes from both scientific and practical opportunities in many fields. The difficulty reflects the issues related to multiscales. Nanofluids involve at least four relevant scales: the molecular scale, the microscale, the macroscale, and the s...

Heat transfer and fluid flow due to buoyancy forces in a partially heated enclosure using nanofluids is carried out using different types of nanoparticles. The flush mounted heater is located to the left vertical wall with a finite length. The temperature of the right vertical wall is lower than that of heater while other walls are insulated. The finite volume technique is used to solve the gov...

Nowadays external magnetic fields are capable of setting the thermal and physical properties of magnetic-nanofluids and regulate the flow and heat transfer characteristics. The strength of the applied magnetic field affects the thermal conductivity of magnetic nanofluids and makes it aeolotropic. With this incentive, we investigate the flow and heat transfer of electrically conducting liquid fi...

In recent years many experimentalists have reported an anomalously enhanced thermal conductivity in liquid suspensions of nanoparticles. Despite the importance of this effect for heat transfer applications, no agreement has emerged about the mechanism of this phenomenon, or even about the experimentally observed magnitude of the enhancement. To address these issues, this paper presents a combin...

In the present study, heat transfer characteristics, namely, coefficient, Nusselt number, pressure drop, friction factor and performance evaluation criteria are evaluated for water, Al2O3 Al2O3/Cu nanofluids. The effects of Reynolds volume fraction composition nanoparticles in hybrid nanofluid analyzed all characteristics. single particle nanofluids flowing through a plain straight tube which i...
