A simple argument based on self-similarity is used to derive a relatio
nship between pointwise energy-dissipation-rate moments, (epsilon(q)),
and inertial-range volume-averaged moments, (epsilon(r)(q)), in homog
eneous, isotropic and stationary turbulence. These results support the
multifractal description of energy dissipation. The moment relationsh
ip implies that pointwise and inertial-range volume-averaged energy-di
ssipation rates cannot both be lognormally distributed. Some pointwise
moments may not even exist if the volume-average counterpart is logno
rmal. The Schwartz inequalities for moments satisfying the self-simila
r relationship are examined and support the realizability of such proc
esses.
