Unsteady nonlinear convection on Eyring-Powell radiated flow with suspended graphene and dust particles

This research contemplates the flow and heat transport of MHD rheological Eyring-Powell fluid embedded with dust and graphene nanoparticles (GP) in an ethylene-glycol (EG) mixture in the presence of nonlinear convection, Cattaneo-Christov heat flux, and thermal radiation. Primarily existing PDEs (fluid and dust phase) are transferred to non-dimensional form by invoking similarity transformations then solved numerically through RKF-45 method. The graphene particles are significantly used in energy transmission in aerospace, power and propulsion generation etc. Through graphical illustrations, velocity and temperature profiles (fluid and dust phases) converse for various prominent parameters. The results of friction factor and heat transfer rate are presented and analyzed. Validation of the present result is made with the existing data. Results demonstrate that increasing nonlinear convection parameter has an inverse relationship with the Nusselt number and the velocity in the dust and fluid phases. This may happen due to the domination of unsteadiness in the flow.
