METHOD AND DEVICE FOR DETERMINING THE INTERFACIAL AREA IN A DIPHASIC MIXTURE COMPRISING A GAS PHASE IN A BUBBLE FLOW

摘要

METHOD OF DETERMINING THE INTERFACIAL AREA IN A VOLUME CONTAINING A DIPHASIC MIXTURE COMPRISING A LIQUID PHASE 3A AND A GAS PHASE IN FLOW IN THE LIQUID PHASE IN THE FORM OF BUBBLES 3. / P P ON DETERMINED, FOR THE SAME PATH OF A SUITE OF ULTRASONIC ACOUSTIC WAVE TRAINS 15, 18 ISSUED AT CONSTANT AMPLITUDE IN THIS VOLUME, THE AVERAGE RATIOS OF THE MAXIMUM AMPLITUDES OF WAVE TRAINS RECEIVED AFTER THE CROSSING OF THE DIPHASIC MIXTURE AND AFTER TRAFFIC IN THE LIQUID PHASE ONLY AND ON THE REPORT THEREFORE DETERMINED ON A CALIBRATION CURVE 1 TRACED EXPERIMENTALLY AND GIVING THE VALUE OF THE INTERFACIAL AREA ACCORDING TO THIS REPORT. / P P APPLICATION TO THE DETERMINATION OF THE CONTACT SURFACE BETWEEN GASEOUS BUBBLES AND THE LIQUID PHASE BY VOLUME UNIT IN A BIPHASIC GAS-LIQUID ENVIRONMENT. / P
