Abstract

The present study analyzes nanofluid flow over a two infinite rotating disk. A magnetic field addressed on momentum equation. An effect of homogeneous-heterogeneous reaction on the fluid flow is investigated. The relevant system of governing equations is transformed into ordinary differential equations by using Von Karman transformations. Homotopy approaches for different physical parameters are examined graphically on appropriate profile. For greater (S₁) the radial, axial and azimuthal velocities are hiked. Energy of liquid enhances with increasing thermophoresis parameter Nt. Local Skin friction coefficient diminishes with higher Reynolds number at lower disk and opposite behavior at upper disk. Moreover concentration field elevates while increasing heterogeneous parameter.
