Add to ORKGA new computational framework for the numerical simulation of turbulent flows through complex domains and along irregular boundaries is presented. The geometrical complexity is included by introducing explicit fractal forcing. This involves the agitation of a spectrum of length-scales and forms an integral part of the flow modeling. The potential application of such a modeling approach is illustrated by the evaluation of the turbulent mixing of a passive scalar field, driven by this turbulent flow. The surface-area and wrinkling of level-sets of the scalar field are monitored showing the influence of the forcing localization on the mixing efficiency
