Investigation of the flow behavior of a water-based hybrid nanofluid containing silver and titanium oxide nanomaterials between two angular rotating disks: A numerical approach

Abstract

Hybrid nanofluid models have the potential to significantly enhance heat transport in many applications, like coolant of electric devices, thermal energy storage, and heat exchangers. Therefore, the existing problem deals with the simulation of heat and mass transport due to the three-dimensional hybrid nanoliquid flow amid two gyrating disks containing silver Ag and titanium oxide TiO2 nanoparticles. Further, a magnetic field is employed normally to flow’s direction. Applications of Darcy–Forchheimer law are discussed in terms of the porous medium. The utilization of the Cattaneo–Christov model is considered for analyzing heat and mass transmission. Additionally, the influence of thermal radiation, non-uniform heat sink/source, and Brownian diffusivity are discussed in the flow analysis. The problem is designed on the basis of the higher-order nonlinear PDEs which are then converted to ODEs using appropriate variables. Using the numerical technique known as the shooting technique in MATLAB, the reduced mathematical structure is solved numerically. From this study, it is analyzed that the axial velocity profile is weakened near the upper disk but the axial velocity profile is amplified near the lower for upsurge in the magnetic factor and porosity parameter. Hybrid nanofluid concentration is lower for higher Schmidt numbers.
