## On the decay exponent of isotropic turbulence It has long been observed that after a short initial transient period of time the decay of the velocity fluctuations u 2 of high Reynolds number homogeneous isotropic turbulence follows closely the algebraic law u 2 βΌ t -n . From experiments and DNS
An experimental investigation of scaling laws in turbulence generated by a biplane grid for low Reynolds numbers (Rex) is presented. The present study covers a wide range of flow field conditions (from Rex ~ 2.5 to Rex,,~ 36) that have not been analyzed from this point of view. It is shown that foll
