Impact of Equally Diffusive Chemical Reaction on Time-Dependent Flow of Casson Nanofluid Due to Oscillatory Curved Stretching Surface with Thermal Radiation

This research investigates the effect of heterogeneous and homogeneous chemical processes on time-dependent boundary layer flow of Casson nanofluid on a stretchable curved oscillating surface in the presence of magnetic field. Using the Buongiorno nanofluid model, the impact of thermophoresis parameter and Brownian motion is investigated. The effects of thermal radiation are also incorporated in the heat equation. The entire flow model is developed by making use of curvilinear coordinate system. The homotopy analysis approach is used to obtain an analytical solution in the form of series solution for the governing system of nonlinear partial differential equations. An in-depth investigation is conducted to determine the influence of various involved parameters on velocity, pressure, temperature, Sherwood number, rate of skin friction coefficient and heat transfer through graphs and tables and discussed in detail. Furthermore, the obtained results are also validated with the published data in the literature as a special case and are found in good agreement. It has been noted the magnitude of skin friction coefficient is decreased with an enhancement in a radius of curvature and Casson fluid parameter. However, it rises as the magnetic parameter and ratio of the surface oscillating frequency to its stretchable rate parameter are increased.
