BASE PRESSURE OSCILATIONS
We consider different methods of calculation of bottom pressure based on the concept of dividing streamline. The concept of quasi-stationary fluctuations, developed by Soviet authors. The information about various phenomena (acoustic, vortex, turbulence, consumables), causing ripple bottom pressure. The main hypothesis of excitation of low-frequency vibrations. Are the most important information on modes of low frequency oscillations in the channel bottom pressure.
