摘要: A numerical investigation to elucidate thermal behavior of hybrid nanofluids consisting Al2O3 and Cu nanoparticles at ratio 90:10 was conducted. Numerical domain a two-dimensional axisymmetric copper tube with length 1000 10 mm in diameter is used. uniform axial velocity assigned the inlet based on Reynolds number. The outer wall consists non-slip condition constant heat flux. assumptions this analysis are; (1) there steady state analysis, (2) effective thermo-physical properties nanofluid are depend volume concentration, (3) fluid continuum. It found that dominant nanoparticle strongly influences nanofluids. also transfer coefficient increases as concentration base fluids
