Abstract

Abstract

Nanoparticle transport and deposition in bends with circular cross-section were solved for different Reynolds number and Schmidt number. The perturbation method was used to solve the equations. The results show that the particle transport patterns are similar and not dependent on the particle size and other parameters when suspended nanoparticles are flowing in the straight tube. Particle deposition at the outside edge is most intensive, and oppositely, the deposition at the inside edge is the weakest. At the upper and lower tube, the depositions are approximately the same for different Schmidt number. Curvatures of tube, Reynolds number and Schmidt number have effects of second order, fourth order and first order on the relative deposition efficiency, respectively.
