The hybrid nanofluids are novel nanofluids and can be made by adding different types of nanoparticles in the plain fluid. The mathematical modeling of hybrid nanofluid under the magnetic influence over a vertical wavy
surface is developed in the present theoretical investigation. The analysis is performed for hybrid nanofluid consisting of Al₂O₃-SiO₂ nanoparticles and compared with SiO₂ nanoparticle. The theoretical results also indicate
that Al₂O₃-SiO₂ water hybrid nanofluid have higher heat transfer rate when compared with SiO₂- water nanofluid. In hybrid nanofluid, the choice of a suitable mixture of nanoparticles can lead to desire heat transfer
phenomena. The implicit finite difference scheme is utilized for solution purposes. Results are presented in tabular and graphical form for the choice of suitable parameters.
