摘要: Laminar-flow convective heat transfer of nanofluid in a circular tube with constant wall temperature boundary condition is investigated numerically. A dispersion model used to account for the presence nanoparticles. Numerical predictions are agreement experimental results obtained our laboratory different particles sizes. Results clearly show that addition nanoparticles base liquid produces considerable enhancement transfer. Heat coefficients increase nanoparticle concentration. Decreasing size at specific concentration increases coefficients.
