The growing need for reliable energy supply to enhance productivity in industrial and residential
sectors underscores the importance of conserving solar energy. This can be achieved through
measures such as optimizing solar collector coatings and optical heat processes. The environmental

the

urgency of seeking alternative solutions. Solar energy has emerged as a highly promising
option, capturing global attention for its potential to improve productivity and sustainability. The
study focuses on examining aluminum alloy-titanium alloy/ethylene glycol hybrid nanofluid in
the flow of non-Newtonian Oldroyd-B through a parabolic trough surface collector located in the
solar water pumps (SWP). The Galerkin weighted residual method was utilized to solve the group
of equations that describe momentum, energy, and entropy generation. The findings show that
the hybrid nanofluid leads to better thermal radiative performance compared to the ordinary
nanofluid. Therefore, the implications of these findings are substantial, particularly in the fields of
thermal engineering and renewable energy. By offering insights into the efficient utilization of
solar energy in water pumping systems and the reduction of entropy generation, this research has
the potential to drive innovations that enhance the sustainability and performance of such
systems.
