Abstract

Mean streaming is often observed in precessing cylinder flows, yet the exact mechanism of its creation remains obscure. By Reynolds-decomposition of the Navier–Stokes equation for a rotating frame of reference, we identify two forcing terms which, when applied to an axisymmetric simulation, generate a streaming flow identical to that obtained from a full three-dimensional simulation. These
terms are (i), the usual Reynolds-stress term, and (ii), a term originating from the Coriolis term. The latter accounts for most of the energy of the streaming flow at small nutation angles.
