A multiaffine fractal interpolation scheme was developed. It was found to preserve not only the fractal dimensions but also the higher-order structure functions. The model was found to have the potential for satisfactory performance in large-eddy simulations. The pertinence of the methodology in case of passive scalars was also investigated.
