Abstract
The film condensation of vapor on a cooled, downward-facing surface is a complex dynamic fluid phenomenon. This paper will describe the theoretical basis, instrumentation approach, and experimental results for a method for ultrasonic monitoring of film condensation. The ultrasound measurement system utilizes a 10 MHz broadband contact transducer, operating in pulse-echo mode. By appropriate signal processing, condensation layers over a wide thickness range, from much less than a wavelength to several wavelengths, can readily be measured.
