Abstract
Aim: experimental study of the “crystal-liquid” phase transition in the temperature range from – 10°С до +25°С in a closed system with a “honeycomb” type structure with accumulation of water.
Methodology. Methods of acoustic emission induced by changes in the external temperature field are used. Under the influence of a changing temperature field, melting of ice crystals occurs inside the honeycomb structure, as a result of which discrete ultrasonic pulses are emitted, which are recorded by an acoustic emission installation for subsequent analysis. Heating is carried out in two ways: (1) by relaxing the temperature of cooled samples to room temperature values; (2) cooled samples receive additional, forced constant heating, thereby increasing the rate of temperature rise.
Results. The dependences of the amplitudes and activity (the number of acoustic emission pulses per unit time) of acoustic signals on time, as well as the frequency distribution of recorded ultrasonic pulses, were obtained. It is shown that as a result of forced heating, signals indicating an “ice-water” phase transition in the honeycombs most clearly appear.
Research implications. The conducted experiments show that the method of acoustic emission at insignificant variations of the temperature field allows to detect a defect in the form of moisture in a closed honeycomb structure.
