The structure of turbulent flow in a rectangular channel containing a cylindrical rod - Part 2: phase-averaged measurements

摘要

In Part 1, we have presented the Reynolds-averaged turbulence characteristics of iso-thermal flow in a rectangular channel containing a cylindrical rod such that it forms a narrow gap with a plane channel wall. Part 2 focuses on conditionally sampled measurements of the phase-averaged characteristics of the coherent vortical structures that produce how pulsations across the gap and formulates a tentative physical model of their typical shapes.
