Abstract

Engineers are finding more and more uses for sophisticated electrostatic nano-coatings. This new information prompted us to look into the theoretical and computational aspects of an unsteady EMHD incompressible two-dimensional heat-transfer tangent hyperbolic ternary hybrid nanofluid boundary layer coating flow outside of a two-dimensional porous wedge surface with implication of Forchheimer- Darcy medium. The effects of electrical and magnetic fields, as well as the effects of surface/injection, suction, and zeta-potential, are taken into account. The boundary conditions for convective heat transfer are analyzed. The watery base fluid (H_2 O) is combined with three metallic nanoparticles (Fe,Cu and Ag) to form the ternary compound nanofluid. Using suitable similarity variables, the controlling conservation partial differential equations for continuity and momentum and their related boundary conditions at the wedge surface and unconstrained stream are changed. MATLAB is used to computationally answer the arising ordinary differential nonlinear boundary value problem. Previous research is used to verify the results. With the aid of visual aids, the effects of the controlling factors on the fluid movement and heat transmission properties are explored and debated. Both the positive and negative values of the electric field are considered in the discussion of the findings. For high values of the rheological parameter and Forchheimer number in both positive and negative electric fields, the velocity dispersion drops. The skin friction coefficient enhanced for the increasing values of the zeta potential parameter and suction/injection parameter. The temperature distribution increases for the large value of the heat source/sink parameter and Brinkman number in both the positive and negative values of the electric field. The Nusselt number decays due to an increment in the permeability parameter.
