Thermal enhancement due to hybrid nanofluid (AA7072–AA7075) containing different metallic particles with solar collector applications

Abstract

Solar collectors are modern types of heat transmission devices which enhance the thermal process with radiative phenomenon. It is experimentally justified that thermal impact of solar collectors is improved with the addition of hybrid nanoparticles. The aim of the current investigation is to enhance thermal phenomenon by using special types of magnetised alloy nanoparticles, namely AA7072–AA7075 with water as the base fluid. For a thermally developed flow, AA7072 contains a uniform suspension of 98% aluminium (Al) and 1% zinc (Zn) and the rest, copper (Cu), iron (Fe) and silica (Si). AA7075 contains aluminium (90%), zinc (5–6%), manganese (Mg) (3%), Cu (1%) and the rest of the suspension is associated with Mn, Si and Fe nanoparticles. The radiative phenomenon is also considered. The source of the flow are two parallel plates placed at a fixed distance. After addressing the modelling of thermal flow problem, the variation of parameter method (VPM) is implemented. The improvement in thermal features of the base fluids by varying the flow parameters is visualised. Current results offer applications in the solar collectors, heat transfer devices, energy systems, solar production, extrusion systems and industrial framework.
