Entropy generation of turbulent Cu–water nanofluid flows inside thermal systems equipped with transverse-cut twisted turbulators

In the present study, numerical simulations have been carried out on thermal characteristics and second-law analysis of turbulent Cu–H 2 O nanofluid flow with the nanoparticle volume fraction of 0 < ϕ < 1.5 % inside heat exchangers fitted by transverse-cut twisted tapes (TCTTs) with alternate...

Description
Summary:In the present study, numerical simulations have been carried out on thermal characteristics and second-law analysis of turbulent Cu–H 2 O nanofluid flow with the nanoparticle volume fraction of 0 < ϕ < 1.5 % inside heat exchangers fitted by transverse-cut twisted tapes (TCTTs) with alternate axis. The transverse-cut ratios are in the range of 0.7
