摘要

This paper will detail experiments conducted using an array of multiple wall skin friction sensors employed simultaneously with a wall normal traversing hot-wire to capture the 'footprint' of large scale motions in a turbulent channel flow. It is shown that these very large scale structures extend all the way to the wall and are influenced by (or influence) the behaviour of the wall shear stress. Experiments are carried out at a Reynolds number of Re_(T) velence 1000.
