A New High-Order Method for Simulating Turbulent Pipe Flow
Fully developed incompressible turbulent flow in a smooth pipe is an important, but yet canonical problem in fluid mechanics. During recent years, large experimental (Talamelli et al. Fluid Dyn. Res. 41:021407, 2009 ) and numerical (El Khoury et al. Flow Turbul. Combust. 91:475–495, 2013 ) interest has shown a number of open questions, in particular related to the scaling of mean and fluctuating quantities, but also to explain similarities and differences to the other canonical wall flows (channels, boundary layers). Most previous numerical efforts towards simulating pipe flows were based on low-order discretisation schemes, motivated by the potential difficulties in the pipe centre, and the need to resolve the numerical singularity. Nevertheless, also a number of high-order methods, based on either radial Chebyshev discretisation, or spectral elements, have been proposed, and used successfully.
