Comparative thermal examination of water conveying aluminum oxide, copper and nickel nanoparticles subject to stagnation point flow

Abstract

The ternary-hybrid nanofluids are impressive sub-class of nanomaterials with enhanced thermal features. Based on such improved thermal characteristics, various applications of such materials are being predicted in the thermal efficiency systems, extrusion mechanism, solar collectors, nuclear processes, energy production and many. The objective of this investigation is to report the comparative thermal analysis for traditional nanofluid, hybrid nanofluid and ternary-hybrid models with water base fluid. The ternary nanomaterials are consisting of nickel, aluminum and copper metallic particles. The exploration of heating capacitance is updated with radiative phenomenon. Moreover, the flow is associated to the stagnation point applications via vertically moving cylinder. The thermal properties for each nanofluid model along with mathematical expressions are characterized in tabular form. The nonlinear system representing the thermal model is numerically solved via most impressive technique namely Keller Box scheme. It has been noted that the tangential velocity component declined with larger values of stretching ratio parameter. It is claimed that the thermal performances of ternary-hybrid nanoparticles are more impressive as compared to nanofluids and hybrid nanomaterials. The temperature profile reduces for stretching ratio parameter which is relatively slower for ternary-nanofluid. The simulated results present significance in various heat transfer systems, heat transfer devices, thermal systems, super-capacitors, extrusion processes, automotive engines, heat exchangers, cooling of computer chips etc.
