Thermal performance of radiative magnetohydrodynamic Oldroyd-B hybrid nanofluid with Cattaneo-Christov heat flux model: Solar-powered ship application

The demand for efficient applications of solar energy and nanomaterials has grown significantly in recent years due to industrial needs and the desire to minimize energy consumption and costs. However, the efficiency of photovoltaic cells and solar-powered ships is highly dependent on solar radiation. In this study, a model for the installation of a parabolic trough surface collector (PTSC) was developed to achieve high temperatures on solar-powered ships. The current study analyzed the thermal characterization function in solar-powered ships under the effect of heat radiation, magnetic field, and viscous dissipation by employing hybrid magnetite particles (Fe3O4) and silver (Ag). The Cattaneo-Christov model has been used to assess heat flux in the thermal boundary layer. The Galerkin weighted residual method (GWRM) has been employed to solve the ordinary differential equations using MATHEMATICA 11.3 software. The findings showed that the thermal efficiency of the hybrid nanofluid was significantly enhanced by 56.3% relative percentage. The motto of the current investigation is developing a model for the installation of PTSC on solar-powered ships under various provided assumptions.
