Abstract
Direct numerical simulations of the turbulent pipe flow of powerlaw fluids are analysed in order to understand the way in which shear thinning affects turbulence. For a generalised Reynolds number of 7500, as the fluid becomes more shear thinning, the log-layer mean velocity profile deviates further above the Newtonian case. Second-order turbulence statistics show a decrease for all correlations except for the axial turbulence intensity which increases marginally over its Newtonian counterpart. The results show that the turbulent kinetic energy budget is modified by new terms that arise in the energy equation.
