摘要: In this paper, results obtained by the numerical investigation on laminar mixed convection in triangular ducts, filled with nanofluids, are presented order to evaluate fluid dynamic and thermal features of considered geometry considering Al2O3/water based nanofluids. The system is heated a constant uniform heat flux also along perimeter duct section H2 mode as boundary condition single-phase model has been assigned for Reynolds number value equal 100. Results given different nanoparticle volume concentrations Richardson values ranging from 0% 5% 0 5, respectively. Results, fully developed regime flow, show enhancement average convective transfer coefficients increasing particle fractions. However, wall shear stress required pumping power profiles increase expected. PEC analysis showed that use nanofluids con...
