Abstract In this paper, we test the local isotropy of higher order statistics in the intermediate wake region. We focus on normalized odd moments of the transverse velocity derivatives, on the wake centreline, which should be zero if local isotropy is satisfied (n is a positive integer). It is found that the relation is supported reasonably well by hot-wire data up to the seventh-order ( ), although it is also dependent on the initial conditions. In particular, the present data show that the higher the order (e.g. fifth- or seventh-order), the higher must be for local isotropy to be satisfied (i.e. ).
