This study numerically investigates the three-dimensional, unsteady mass and heat transfer behavior of tri-hybrid nanofluids over a rotating permeable disk. The nanofluid consists of single-walled carbon nanotubes, silver (Ag), alumina (Al2O3) and water (H2O) as base fluid. Effects from a heat source, chemical reaction, thermal radiation and magnetic field are incorporated.
The governing equations are transformed into ordinary differential equations using similarity transformations and are numerically solved via the finite element method. Graphs illustrate the impacts of the various influencing parameters, such as stretching ratio, chemical reaction, heat source, radiation, unsteadiness, porosity, magnetic parameters and nanoparticle volume fractions (?1, ?2, ?3) on axial and tangential velocity profiles, temperature and concentration distributions.
Tables present their influences on Sherwood number, heat transfer rates and velocity gradients. Key results show that temperature profiles in the tri-hybrid nanofluid increase with higher values of (?1, ?2, ?3).
