Kinematic models for 2D and 3D velocity fields of homogeneous isotropic turbulence are considered. Numerical simulation is performed to obtain a number of independent realisations of the field and some two-point statistics are computed and discussed. The statistics include the velocity correlations and the spectral energy density.
