报告简介：

As is known, a decrease in temperature leads to a change in the aggregate state of the liquid. In this case, at a certain temperature, a phase transition of the first kind occurs, and the liquid turns into ice. Depending on the type of liquid and its chemical composition, such a phase transition can occur at different temperatures and pressures. Monitoring this process is an important practical task both for various mechanisms operating under extreme temperature conditions (ships, airplanes, etc.) and due to climate change, which leads to the melting of permafrost and the corresponding threat to existing infrastructure. In this regard, our group is conducting research on the possibility of using acoustic methods to control this process. It is proposed to use both waves in plates and structures and volumetric acoustic waves. Methods of simultaneous control over the freezing process of various liquids and the uniformity of the resulting ice are proposed. The report will consider both the theoretical aspects of this task and the recently obtained experimental results.

Iren E. Kuznetsova graduated from Saratov State University in 1988 (physics of plasma) and received the Master's degree. In 1996, she received the Degree of Candidate of Sciences (Physics- Mathematics) (Ph.D.) from Saratov State University, Russia. In 2004 he has received the Doctor of Science diploma. Since 1988 and until 2012, she has been working at the Kotelnikov Institute of Radio Engineering and Electronics of the Russian Academy of Sciences, Saratov Branch, as an engineer (1988 to 1991), then as Junior Research Scientist (1991 to 1997), then as Senior Research Scientist (1997-2004), and as a Leading Research Scientist (2004 to 2012). Since 2012 and until the present time she has been working at the Institute of Radio Engineering and Electronics of the Russian Academy of Sciences (Moscow) as a Leading Research Scientist. Since 2015 and until the present time she has been working as a Head of Post-Graduate Study Department of Kotelnikov IRE of RAS. In February 2016 she was elected as Professor of Russian Academy of Science.
