Enhanced heat transfer efficiency of PTSC using hydromagnetic cross nanofluid: A hydrogen energy application

Abstract

Nowadays, the foremost thermal source from the sun is solar energy. The current study deals with the enhanced heat transfer of Parabolic Trough Solar Collector (PTSC) using thermic radiation, space-dependent heat source, and nanotechnological energy. For this, we considered water-based graphene oxide (GO) and alumina alloy (AA7075) mixtures flow through PTSC fitted inside the solar wings of aircraft (Fig. 1). A theoretical Maxwell nano model is adopted by incorporating the thermic radiation and space-dependent heat source/sink effects in the energy equation. The pressure drop caused by the fluid-solid interactions is evaluated by introducing the Darcy-Forchheimer condition. The modeled problem is resolved numerically by applying suitable similarities. The impact of various physical constraints on flow and thermal fields are estimated for water-GO and water-GO-AA7075 fluids and found that water-GO-AA7075 hybrid nanoliquid effectively enhances the thermal performance of PTSC in the presence of thermic heat. Darcy-Forchheimer parameter effectively regulates the momentum and energy fields of hybrid nanoliquid.
