Ariyaratne at the early stage of the research and the advice provided by Professor P. Orlandi on numerical methods. Mr B.S. Oluwadare assisted with the experiments. The research was principally funded by EPSRC through grant EP/G068925/1. This work made use of computing facilities of the N8 HPC and ARCHER, funded by EPSRC through the N8 consortium (EP/K000225/1) and the UK Turbulence Consortium (EP/L000261/1), respectively. S.H., A.E.V., T.OD. & D.P. initiated the research. S.G. designed the test rig with contributions from all other authors, and conducted preliminary experiments. M.S. wrote the DNS code. A.M. together with M.S. implemented LES in the code. A.M. conducted the experiments and LES simulations. S.H., A.M., M.S. & S.G. analysed the results. S.H. led the writing of the manuscript with contributions from all other authors. A.M. & S.G. made equal contributions.201049921engPipe flow boundary layer < Boundary LayersTurbulent transitionturbulence theoryTA Engineering (General).
