摘要: Abstract Convective heat transfer of Al2O3–water nanofluid over an equilateral triangular obstacle with optimization analysis is carried out to determine the optimum conditions for maximum rate and minimum drag coefficient. Orientations obstacle, values solid volume fraction, Reynolds number are selected as input parameters. The performed according Response Surface Methodology. response surface equation obtained using design experiments features. Two-dimensional unsteady equations relevant boundary have been solved finite method. Three different orientations defined procedure. computational simulations done numbers ( 1 ≤ Re 180 ), fractions 0 φ 0.05 ) ° θ 60 ). Also, a comparison between results CFD It found that coefficient occurred at θ = 35.13°, Re = 97.6 φ = 0.01 Nusselt θ = 8.49°, Re = 180 φ = 0.05.
