Simulation for impact of new tapes on behavior of nanomaterial within a pipe with considering turbulent regime was scrutinized in current attempt. Entropy analysis was divided into two parts and both fractions were presented in contours. Evaluating the performance of unit should be done in the form of productivity and irreversibility. Presence of new shape of tapes can augment the swirl flow and such greater turbulent intensity can provide better performance. Adding nano-powder can decline the irreversibility and augment the thermal features. In low range of Re, S gen,th is 200 times larger than the amount of S gen,f . As pumping power augments, the temperature reduces by about 1.41% when β  = 0. Nu and Darcy factor increase by about 1.03% and 8.87% with the rise of β when R e = 5000. Increase of inlet velocity at the highest β leads to 46.5% augmentation in Nu, while f declines by about 11.04%.
