Abstract: In this study, a thermal energy extrusion system was made by an improved parameters effect controlling method to promote the manufacturing economic efficiency. The present investigation problem is composed of activation energy electrical MHD Ohmic dissipation and mixed convection of a viscoelastic non-Newtonian Carreau-Nanofluid on a stagnation-point energy conversion problem. The governing equations for thermal energy extrusion system are solved by analysis and implicit finite difference method. The thermal system is composed of flow velocity field, temperature field, mass diffusion field and heat conduction-convection field. The related important parameters have been produced as function of the fluid material parameter (λ), activation energy chemical reaction parameter (λA), Prandtl number (Pr) and mixed convection buoyancy parameters (Gc, Gt), etc. The results are shown that it will be provided greater thermal system effects with larger or lower values of those parameters, and have been divided six degree sequences to show their importance at this system. At last, it can be obtained a higher efficiency thermal energy extrusion system and can be promoted the system's economic efficiency.
