Abstract
The analysis of an advanced ternary nanofluid with different nanoparticle shapes in stretchable convergent/divergent channels with the same slope of equal magnitude is a topic of paramount significance at the current time. Therefore, a new heat transport model of a ternary nanofluid is developed under innovative effects of the magnetic field (Ha), thermal radiation (Rd), heat absorption/generation (Q1⟨0,Q1⟩0) and stretching/shrinking (S1>0,S1<0) effects developed. To acquire the fine heat transfer results, an efficient numerical scheme, the Galerkin Finite Element Method is implemented and the heat transfer results are furnished under the physical ranges of the aforementioned parameters. It is analyzed that heat generation Q1>0, Rd and stronger dissipation effects Ec contributed potentially to thermal enhancement in the ternary nanofluid for convergent/divergent walls with stretchable effects. The absorption and Joule heating effects are good to control the heat and also a significant increase in Nusselt number is observed for the ternary nanofluid containing blade nanoparticles.
