METHOD AND APPARATUS FOR EXERCISING INFLUENCE ON THE BOUNDARY LAYER OF A BODY SUBJECTED TO MAINLY STOCHASTIC FLOW FLUCTUATIONS

摘要

IN THE PROCESS AND DEVICE ACCORDING TO THE PRESENT INVENTION, THE FLOW OF A FLUID IS INFLUENCED IN THE BOUNDARY LAYER OF A BODY ON WHICH THESE FLUID FLOWS IN ORDER TO REDUCE THE RESISTANCE AND PREVENT SEPARATION OF THE FLOW. DURING THE PRIMARILY STOCHASTIC FLUCTUATIONS OF THE SAID FLOW. FOR THIS, WE DETECT THE FREQUENCY OF THE FLOW IN A SENSOR 1, WE TRANSMIT THE DETECTED VALUE TO AN ANALYZER 3 WHICH IN TURN PROVIDES A SIGNAL TO A TRANSMITTER 2 OF VIBRATIONS TO INTRODUCE A VIBRATION IN THE FLUID FLOW IN VIEW TO DAMAGE OR AMPLIFY THE FLOW AND A PERIODIC VIBRATION OF THE SAME FREQUENCY IS SUPERIMPOSED ON THE PREDOMINANT STOCHASTIC FREQUENCY.
