ABSTRAKT

DNSs and experiments were carried out for a turbulent channel flow of a 75 ppm CTAC (Cetyltrimethyl ammonium chloride) surfactant solution. The numerical and experimental results such as velocity profiles, root-mean-square velocity fluctuations, Reynolds shear stress, and production of turbulent kinetic energy were compared. The results were also compared with those of Newtonian fluid flow at similar Reynolds numbers.
