Raising thermal efficiency of solar water?pump using Oldroyd?B nanofluids' flow: An optimal thermal application

It is well known that solar energy the main source of thermal coming from sun responsible for huge operations in engineering studies. can be seen technology photovoltaic cells, streetlights, plates, and water pumping. This study investigating radiation as a method to improve performance pump (SWP) with use along nanotechnology. The transfer checked case many impacts including heat radiations variable conductivity. An Oldroyd-B nanofluid entropy production analysis has been scrutinized working coolant liquid system. Graphene oxide (GO) Cu nanoparticles have employed engine oil (EO) base liquid. noticed SWP increases amplification temperature-dependent conductivity characteristics. In comparison low nanofluid, high provides best capability transmission. efficiency used (GO/EG) enhanced by between 7.70% 26.68% than (Cu/EO) nanofluid.
