The current inquiry analysed the turbulent flow pattern of power-law fluids to shed light on the critical turbulence characteristics of non-Newtonian fluids. The flow behaviour index of the power-law fluid in the current investigation was set at 0.75, 0.8, 1, 1.2, 1.4, and 1.6 at a simulation's Reynolds number of 12,000. This investigation was focused on large eddy simulation of turbulent pipe flow of pseudoplastic and dilatant fluids passing through an axially stationary pipe. The results point to a significant increase in the generation of axial turbulence and a noticeable decrease in the transfer of tangential and radial turbulence intensities from the axial intensities with a drop in the flow behaviour index. A substantial reduction of the turbulent kinetic energy and the Reynolds shear stress of velocity variations in the radial direction was another effect of the lower flow behaviour index.
