  In this work, we implement a new experimental configuration which exploits
the specific properties of the optical bistability exhibited by the polariton
system and we demonstrate the generation of a superfluid turbulent flow in the
wake of a potential barrier. The propagation and direction of the turbulent
flow are sustained by a support beam on distances an order of magnitude longer
than previously reported. This novel technique is a powerful tool for the
controlled generation and propagation of quantum turbulences and paves the way
to the study of the hydrodynamic of quantum turbulence in driven-dissipative 2D
polariton systems.
