The ABS Acoustic Bubble Spectrometer (ABS) is useful in a variety of two-phase flow applications where knowledge of the bubble size distribution and the volume fraction of gas in the liquid are important. These areas include oceanography, chemical engineering, controlled laboratory testing (particularly where cavitation or boiling are possible and the underlying bubble nuclei distribution must be known), industrial flows, specialty fluids based on gas/liquid mixtures, aeration, heat exchangers, and biomedical instrumentation. The instrument provides the data in near real time, thus making it suitable for process or time varying applications. The ABS is built around a PC Windows platform and includes high-speed cards for signal generation and data acquisition. A pair of hydrophones or transducers transmits and receives a series of short monochromatic bursts of varying frequencies from which the attenuation and phase speed in the bubbly liquid are determined. These signals are processed and analyzed with proprietary software algorithms that solve the mathematically ill-posed inverse problem and obtain the bubble size distribution and void fraction.
