摘要: Nanofluids can afford excellent thermal performance and have a major role in energy conservation aspect. In this paper, sensitivity analysis has been performed by using response surface methodology to calculate the effects of nanoparticles on entropy generation. For purpose, laminar forced convection Al2O3-water nanofluid flow inside channel is considered. The total generation rates consist due heat transfer friction loss are calculated velocity temperature gradients. continuity, momentum equations solved numerically finite volume method. rate different parameters such as solid fraction, particle diameter, Reynolds number studied detail. Series simulations were for range fraction 0 ≤ ϕ 0.05 , diameter 30 nm d p 90 nm 200 Re 800. results showed that more sensitive rather than or fraction. Also, magnitude generation, which increases with increase number, much higher pure fluid nanofluid.
