Simulation of swirl flow intensification with the use of new device inside a pipe was performed in the current investigation. To improve the feature of testing fluid, hybrid nanopowders were dispersed. Outputs were exhibited in terms of contours. Tangential velocity of nanomaterial augments with the increase in Re, and stronger convective mode is obtained with the rise in Re. Thinner thermal boundary layer close to the wall is an output of reducing pitch ratio and leads to greater Nu. Augmenting contact surface area with a decline in pitch ratio leads to stronger secondary flow.
