dc.description.abstractTurbulent convective heat transfer and Fe3O4/water nanofluid flow behaviors in a corrugated tube were studied numerically. The numerical study was performed using the corrugated copper tube with a 10.70 mm inside diameter with a constant heat flux boundary condition. The finite volume approach was used to discretize the Eulerian two-phase model and then solve it using the SIMPLE technique. The effect of corrugated pitch and corrugated depth on the velocity vectors and temperature contours are presented and analyzed. It was found that the geometrical parameters (corrugated pitch and corrugated depth) have a significant effect on the velocity and temperature contours. In comparison to the plain tube, the maximum and minimum turbulent intensity enhancements are 1.40 and 1.06 times, respectively, also resulting in an increase in the Nusselt number enhancement. Simultaneously, due to more flow complexity and roughness augmentation, the flow resistance also increased. © 2021 Taylor & Francis Group, LLC.
