Field-synergy and nanoparticle’s diameter analysis on circular jet impingement using three oxide–water-based nanofluids

The field synergy study is carried out using three oxide nanofluids impinging circular jet on the horizontal disc to analyse synergetic interaction of cooling processes between temperature and flows fields. h eat transfer effect o f nanofluid examined by rising Reynolds number nanoparticle concentration depending number. For impinged process, scale flow speed decayed with increase Hence, it contributed a lower heat efficiency nanofluid. Whe reas, can be enhanced particle concentration. Thus, increased. Analysis showed that Al2O3 has maximum relative among selected nanofluids. It evident concentration, material have significant augmentation. In addition, explored varying jet-disk spacing. Moreover, investigation shown reducing for materials Al2O3, CuO TiO2 subsequently. revealed enhancement higher smaller nanoparticle’s diameter (i.e., 20 nm) than bigger 80 same material.
