Thermal analysis characterisation of solar-powered ship using Oldroyd hybrid nanofluids in parabolic trough solar collector: An optimal thermal application

Abstract The mathematical modeling of hybrid nanofluid flow and heat transfer with entropy generation toward parabolic trough surface collector (PTSC) inside the solar-powered ship (SPS) is performed. model used non-Newtonian Oldroyd-B amidst a constant inclined magnetic field influence being considered. then reduced by adopting appropriate similarity transformation into higher-order nonlinear differential equations system. computed using well-known technique called Keller Box scheme. Physical parameters effectiveness, for instance, thermal radiation, viscous dissipation, nanoparticles, Joule heating, displayed in graphs. silver-ethylene glycol (Ag-EG) characteristic performance outperformed silver-magnetite-ethylene (Ag-Fe 3 O 4 /EG). maximum efficiency Ag-EG about 26.3%, while minimum at least 5.6%.
