Peristalsis of CuO–TiO 2 /water hybrid nanofluid with ion-slip and Hall currents effects induced by electroosmosis

This study investigates the peristalsis of CuO - TiO 2 / O 2 O hybrid nanofluid via two-dimensional asymmetric channel. The flow is induced by the electroosmosis and influenced by electromagnetic effects, that is, ion-slip and Hall currents. A mathematical model is considered to explore the nature of nanoparticles volume fraction and temperature on viscosity of hybridized nanomaterial. Governing equations are solved by using the lubrication theory and the assumptions of Debye-Huckel linearization. Numerical solutions for arising system are achieved by adopting numerical approach namely shooting scheme in Mathematica. Computations for velocity, temperature, and heat transmission rate are presented through different zeta potentials. Outcomes revealed that the heat transmission rate increases when higher values of zeta potential at right wall are considered. The results also indicated that heat transfer rate can be enhanced up to 5.6% for the solid concentration range of 0.01 – 0.10. Hybrid nanofluid has greater velocity for negative value of Helmholtz-Smoluchowski velocity U hs .
