Abstract
The paper focuses on the study a special type of boiling, "microbubble boiling". Experiments are carried out on water-ethanol mixtures of different concentrations. The pressure varies from 0.1 to 0.3 MPa; and copper and stainless-steel samples are used as working samples. The purpose of the experiments is to investigate the effect of such parameters as solid and liquid properties and subcooling on the transition temperature from the stable film boiling to “microbubble” boiling regime. In the course of direct comparison of the results obtained by cooling the samples with different thermal effusivity under the same conditions, a strong influence of the properties of the cooled body on the quenching process has been revealed.
