Numerical thermal study of ternary nanofluid influenced by thermal radiation towards convectively heated sinusoidal cylinder

APPLICATIONS: The heat transfer remains a huge problem for industrialists and engineers because many production processes required considerable amount of heat to finish the process successfully. Although, conventional fluids have large scale industrial applications but unable to provide huge amount of heat transfer. Therefore, the study is organized to propose a new ternary heat transfer model using different physical constraints. The key applications area of nanofluid heat transfer are chemical, applied thermal and food processing engineering. PURPOSE: and Methodology: The key purpose of this research is introduce a new ternary nanofluid model using the impressive effects of thermal radiations, surface convection and saddle/nodal points. The results simulated via RKF-45 and discussed in detail. CORE FINDINGS: The strength of Al(2)O(3) nanoparticles form 1%–7% (keeping fixed CuO and Cu as 4% and 6%) and s(1) = −0.2,-0.4,-0.6,-0.8 controlled the fluid movement while s(1) = 0.2,0.4,0.6,0.8 boosted the velocity. Increasing the convection process B(i) = 0.1,0.2,0.3,0.4 increased the temperature significantly. Further, shear drag is maximum for ternary nanofluid and thermal radiations R(d) = 0.1,0.2,0.3,0.4 enhances the heat transfer rate.
