Abstract

We present a high Reynolds number experiment. The flow takes place in a cylindrical vessel and is confined and forced by two counter-rotating disks. We use two different cells, the dimensions are for the first cell (the second resp): a radius of 3.3 cm (10 cm resp) and a height of 5.5 cm (13.1 cm for the second one). The fluid used is helium gas at low temperature (4.2 to 8 Kelvin). At this temperature, by varying the pressure from 60 mbar to 6 bars, the kinematics viscosity varies over 3 orders of magnitude, and so the Reynolds number varies from 104 to 107 (in term of microscale Reynolds number Rλ, the system explores a range of value from 150 to 3200).
