Direct numerical simulations of fully developed turbulent pipe flows for Reτ=180, 544 and 934

•To simulate turbulent pipe flow with a 30R long streamwise domain at three different Reynolds numbers.•To propose an increasing trend of near-wall peak in streamwise turbulence intensity.•To support the contention, the method of a spatial two-point amplitude modulation covariance was applied. Direc...
