Abstract 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, Sgen,th is 200 times larger than the amount of Sgen,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 Re = 5000. Increase of inlet velocity at the highest β leads to 46.5% augmentation in Nu, while f declines by about 11.04%. Keywords Nanoparticle · Turbulent · Tapes · Tube · Modeling
1. Introduction Adding nanoparticles to typical fluids such as glycol ethylene and water results in nanofluids which have higher rate of conductivity. Such behavior is related to greater conductivity of solids than that of liquids. Also, the thermal resistance of nanofluids within heat transfer decreased due * Quang‑Vu Bach [email protected] 1

to impingement of particles, liquid and pipe wall (Qin et al. 2019a, 2019b; Yu et al. 2020; Zhu et al. 2019). Altering the kind of working fluid can offer new field of science in thermal engineering (Lv et al. 2020; Yu-Ming 2020; Luo et al. 2020a; Chu and Salahshoor 2020; Song et al. 2020). With the use of FEM, Nazir et al. (2019) performed the 3D thermal treatment of fluid and solved the nonlinear flow. Their reason for selecting such method is achieving more accurate solution. With the aim of augmenting secondary flow, Zheng et al. (2020) tried to install multi-tapes within the pipe and they utilized nanomaterial to boost thermal behavior of fluid. Numeri
