Ferrofluids (FF) are colloidal suspension magnetic particles, which have dimensions of about 10 to 100 nm, dispersed in a base fluid
The initial schematic diagram of a partially layered porous square cavity filled with ferrofluid (Fe3O4) under the impact of a variable magnetic field is presented in figure 1
The primary objective of this work is to depict the natural convective of a ferrofluid in a partially layered porous cavity in the presence of an external variable magnetic field for two different cases: 1. The cavity contains a heated sinusoidal wave rod 2
Summary
Ferrofluids (FF) are colloidal suspension magnetic particles, which have dimensions of about 10 to 100 nm, dispersed in a base fluid. Applying the ferrofluid on natural or mixed convection in cavities with or without a partially layered porous is a fundamental problem in fluid mechanics. This flow has various engineering applications such as heat change in a domestic refrigerator, electronic cooling, solar collectors, and microelectromechanical systems.. By using the mixture model and finite volume method, Asadi et al. examined the hydrodynamic and thermal behavior in forced convection of ferrofluid under impacts of a non-uniform magnetic field in a channel Their results can be used for enhancement heat transfer in heat exchangers. The target of this work is to depict the impact of variable external magnetic fields on natural convection of the ferrofluid filled in a partially layered porous cavity.
