Abstract:
Wall-resolved large-eddy simulation of fully developed turbulent pipe flows are performed using a spectral vanishing viscosity approach. Turbulence statistics are compared with direct numerical simulation and hot-wire experimental data at similar friction Reynolds numbers Re = 1002. Turbulence statistics of streamwise velocity show good agreement up to the fourth order. 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. Further simulations have been performed at Re ≈ 2000, preliminary results compared well to DNS data and will be presented in the conference and full paper.
