Abstract
This article scrutinized numerical investigation on turbulent alumina nanomaterial flow through a pipe with insertion of a device for inducing secondary flow. To guess the properties of alumina, single phase model was incorporated. Influence of revolution (N) and diameter (D*) of turbulator as well as pumping power (Re) were illustrated in outputs. More intensive velocity gradient of nanomaterial near the pipe occurs with rise of D* owing to higher back flow. Augmenting N boosted the nanomaterial flow and thinner boundary layer appeared. Flow disturbance near the wall enhances with rise of N and distortion of vortex augments for greater N which results in greater velocity gradient and more resistance. Darcy factor tends to reduce with rise of Re but it tends to increase with augment of revolution. (C) 2020 Elsevier B.V. All rights reserved.
