N2 - Results are reported for wall-resolved-large-eddy simulation of fully developed turbulent pipe flow with computational domain length 8πδ, performed using a spectral vanishing viscosity approach. Turbulence statistics are compared with direct numerical simulation and hotwire experimental data at matched friction Reynolds number Reτ=1002. Turbulence statistics of streamwise velocity show good agreement up to the fourth order. Analysis of the results from the transverse velocities and pressure components are also performed and found to compare well with direct numerical simulation data. The results highlight the feasibility of using wall-resolved-large-eddy simulation to accurately investigate turbulent pipe flow at Reynolds numbers not currently feasible for direct numerical simulation.
