New industrial and didactic flow solutions based on new flow concepts are needed to meet the unprecedented requirements set by the dramatically increasing energy needs, the use of Thermoelectric didactive devices are neded for better environmental and industrial performance. We need improvements to existing solutions, such as better convective control with radical new developments thanks to thermoelectricity coupled with fluid dynamics descriptors such as PIV. also energy savings and reduction of adverse environmental impacts can come from multifractal concepts. The development of new flows both numerically and experimentally are important for solutions with fully resolved simulations because existing turbulence models cannot be applied indiscriminately on many untested new flow ideas. One very recent example is the turbulent flows generated by fractal grids. Fractal grids are made from a structure, such as a square, repeated at different scales that allow higher mixing efficiencies.
