“…The amount of collected water is then weighed to provide a direct LWC measurement. The iso-kinetic condition defines a cylindrical stream tube in a spray cloud with a cross-sectional area equal to the probe's inlet area, hence, each measurement represents a discrete point in a spray cloud distribution [5].…”

The paper is focused on the experimental study of possibilities of the thermoanemometric analysis for determination of the liquid water content in the stream of wet air. The developed method is based on the measurement and comparison of stream velocity of wet and dry air by the hot-wire thermal anemometric probe. Experiments were performed in the small icing wind tunnel using the standard thermal anemometer Testo 425. There was found the correlation between the liquid water content and the difference in measured velocity of the wet and dry airstreams. The conclusion of the paper pays attention for the interpretation and formulation the final analyses and recommendations.

This paper presents a critical development to a prototype sensor that is capable of measuring total air temperature and humidity in a mixed-phase environment, consisting of liquid water droplets and ice crystals. The sensor has fast and stable measurement response under particularly challenging mixed-phase conditions. Total temperature and humidity levels measured with the probe are in good agreement with the results of analytical energy and moisture balances.
