METHOD DETERMINING AVERAGED MEAN SQUARES OF TURBULENT PULSATION OF VELOCITY IN SEA MEDIUM UNDER CONDITIONS OF ADDITIVE VIBRATION NOISES AND DEVICE FOR ITS REALIZATION

摘要

FIELD: study of hydrophysical fields, conducting of ecological investigations, oceanology. SUBSTANCE: invention is intended for those branches of science and technology where tests of parameters of turbulent pulsation of velocity in sea medium are required. Conversion of velocity to electric signal is simultaneously conducted with the use of three velocity-to-electric signal converters which are moved rectilinearly and uniformly is studied medium. Averaged mean squares of turbulent pulsation of velocity in sea medium are found by design formula. Device for realization of method has first velocity-to-electric signal converter, second and third velocity converters identical to first converter placed on one straight line with first converter equidistantly from it and on both sides of straight line. It also includes unit computing function and band-pass filter, squarer and scaling unit connected in series. EFFECT: determination of averaged mean squares of pulsation of velocity with low-level energy of turbulence. 2 cl, 6 dwg
