The critical layer in pipe flow at high Reynolds number.
We report the computation of a family of travelling wave solutions of pipe flow up to Re=75000. As in all lower branch solutions, streaks and rolls feature prominently in these solutions. For large Re, these solutions develop a critical layer away from the wall. Although the solutions are linearly unstable, the two unstable eigenvalues approach 0 as Re-->infinity at rates given by Re-0.41 and R...
متن کاملSurface-sampled simulations of turbulent flow at high Reynolds number
Funding information European Commission Horizon 2020, Grant/Award Number: 671571; Engineering and Physical Sciences Research Council (EPSRC), Grant/Award Number: EP/L000261/1 Summary A new approach to turbulence simulation, based on a combination of large eddy simulation (LES) for the whole flow and an array of non–space-filling quasi-direct numerical simulations (QDNS), which sample the respon...
متن کاملUnsteady RANS Simulation of High Reynolds Number Trailing Edge Flow
Unsteady vortex shedding at a trailing edge may cause pressure fluctuations and strong tonal noise which can have important consequences to the performance of marine and aeronautical type lifting surfaces. This paper presents data from unsteady RANS simulation of high Reynolds number trailing edge flow. It aims to identify and quantify dominant features of the trailing edge flow field over a tw...
متن کاملLinearized pipe flow to Reynolds number 107
A Fourier–Chebyshev Petrov–Galerkin spectral method is described for high-accuracy computation of linearized dynamics for flow in an infinite circular pipe. Our code is unusual in being based on solenoidal velocity variables and in being written in MATLAB. Systematic studies are presented of the dependence of eigenvalues, transient growth factors, and other quantities on the axial and azimuthal...
متن کاملAsymptotics beyond All Orders for a Low Reynolds Number Flow
The solution for slow incompressible ow past a circular cylinder involves terms in powers of 1= log , times powers of 1= log , etc., where is the Reynolds number. Previously we showed how to determine the sum of all terms in powers of 1= log. Now we show how to go beyond all those terms to nd the sum of all terms containing times a power of 1= log. The rst sum gives the drag coeecient and repre...
