Abstract: The present study is based on magnetohydrodynamic forced convective flow over a yawed diverging channel and its fluid properties. Ag and TiO2 are the hybrid nanofluids under study on an irregular boundary. A standard nebulizer lacks in drug wastage and efficiency of drug delivery while, a nebulizer with a yawed diverging channel can improvise these shortcomings due to its geometry. A boundary layer approximation is used to create a flow model such as momentum, energy, and concentration equations. The governing partial differential equations are transformed to nonlinear partial differential equations using similarity transformation. The quasilinearization technique followed by the finite difference scheme is applied to solve the linear equations. The computational results are graphically presented in terms of skin friction coefficient, velocity and temperature profile, and Nusselt number. The skin friction coefficient increases due to the rise in Lorentz force and yawed angle (θ). Velocity profile increases with increased heat source (Q>0), while velocity profile decreases for heat sink (Q<0), and buoyancy forces cause a steady rise in the velocity profile.
