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.
