Abstract
Second-order pressure structure functions, estimated from direct numerical simulations of homogeneous and nonhomogeneous turbulent flows, exhibit a si gnificant Reynolds number dependence in the dissipative range. This depende nce mainly reflects the contribution from low wave numbers to the instantan eous pressure gradient. (C) 1999 American Institute of Physics. [S1070-6631 (99)01301-X].
