Abstract

To exhibit the nanomaterial hydrothermal behavior within a duct, FVM has been utilized and to augment the performance, helical complex device was incorporated. To achieve the formulation of problem, K-ɛ model was applied with considering CuO-water nanomaterial. Outputs in forms of velocity and temperature contours have been extracted. Stronger tangential contact of carrier fluid with outer wall guarantees the thinner boundary layer with rise of inlet velocity and friction loss augments. The increase of turbulator width results in augment of Nu owing to greater tangential flow and more fluctuations.
