AB  - The universality of a passive scalar advected in homogeneous isotropic turbulence is studied by scale-by-scale budget equations for higher order moments. Based on an analytical development of structure functions in the dissipative range, a scaling for higher order structure functions is proposed. A similarity scale analysis is used to show the validity of the proposed scaling in the dissipative range and the inertial range. The analysis is based on highly resolved direct numerical simulations (DNS) with different Reynolds numbers. To this end, a comprehensive DNS data base of turbulence has been created. To resolve all relevant scales of turbulence the grid size is as high as 68 billion grid points. This data base allows a consistent analysis of small-scale turbulence and scaling laws of turbulent flows.
