Increasing heat transfer of non-Newtonian nanofluid in rectangular microchannel with triangular ribs
TLDR
In this paper, solid nanoparticles of Aluminum Oxide have been added to the non-Newtonian fluid in volume fractions of 0.2% with diameters of 25, 45 and 100nm.Abstract:
In this study, computational fluid dynamics and the laminar flow of the non-Newtonian fluid have been numerically studied. The cooling fluid includes water and 0.5 wt% Carboxy methyl cellulose (CMC) making the non-Newtonian fluid. In order to make the best of non-Newtonian nanofluid in this simulation, solid nanoparticles of Aluminum Oxide have been added to the non-Newtonian fluid in volume fractions of 0–2% with diameters of 25, 45 and 100 nm. The supposed microchannel is rectangular and two-dimensional in Cartesian coordination. The power law has been used to speculate the dynamic viscosity of the cooling nanofluid. The field of numerical solution is simulated in the Reynolds number range of 5read more
