Stability Analysis of Magnetohydrodynamic (MHD) Copper Water Casson Nanofluid Flow on a Rotating Vertical Cone with Radiation and Darcy-Forchheimer in a Porous Medium

This is to investigate the effects of copper water (Cu-H20) in two dimensional Casson nanofluid on a rotating vertical cone with radiation and Darcy-Forchheimmer in a porous medium. Flow governing equations are transformed into self-similar equations using similarity transformation. Boundary value problem solver in MATLAB was used to solve the system of reduced ordinary differential equations. The buoyancy opposing flow lead to two different solutions, first solution is stable and physically realizable while the second solution is unstable and unachievable. Validation of the present results with published results are in excellent agreement. Heat transfer enhancement is achieved with increase in concentration of copper-water Casson nanofluid. It is also noticed that increase in radiative parameter attracts increase in temperature of the fluid at the aiding flow. In practice the investigation have real-life and industrial applications, such as cooling electrical devices, biomedical, military, increase in heat generation for manufacturing industries etc.
