Concentration Measurement in Bubbly Liquids - A Matter of Times
Leaky Lamb waves in an acoustic cavity can be utilized for the measurement of temperature, density and sound velocity of an enclosed liquid. If the sensitivity of these variables to a change of predefined components in a liquid mixture is high enough, an online concentration measurement can be utilized as well. Gas bubbles can influence the measurable times-of-flight which can be disadvantageous for the concentration measurement. This paper will show how simultaneous group and phase velocitydoi:10.1016/j.phpro.2015.08.073 fatcat:ynhw2agfmrhangbalxubn5reju
