Academician of the Russian Academy of Sciences, Member of the Presidium of the Russian Academy of Sciences, Dr. Sci. (Phys.-Math.), Professor, Research supervisor, P.P.Shirshov Institute of Oceanology of the Russian Academy of Sciences, Head of the Department of Gas and Wave Dynamics, M.V.Lomonosov Moscow State University (Moscow, Russia).
A world-class scientist in the field of mechanics, the creator of the world-renowned scientific school on the mechanics of multiphase systems. The greatest contribution was made by his work in solving such fundamental problems as mathematical modeling of the dynamics of multiphase media; hydro and gas dynamics of steam and gas-liquid systems; burning, detonation and explosion in dispersed media; filtration of multiphase liquids. He established the laws of propagation of various types of waves (waves of compression, rarefaction, combustion, detonation) in two-phase systems of various structures and discovered a number of new effects. He developed the theory of the rate of deformation of solids in the presence of polymorphic transformations in them, the formation and movement of dislocations, and the hardening of metals under explosive loads. Under his leadership, current research and development has been carried out on the safety of energy and technological systems, new methods of oil and gas production, enhanced oil recovery, increased efficiency and intensification of technological processes in the energy, oil refining, chemical technology explosive industries. Important for the creation of promising technologies are the results obtained by him in the study of the formation and collapse of bubble clusters in cold deuterated liquids with intense acoustic effects. Theoretically predicted the possibility of achieving ultrashort pressure surges and temperatures close to the conditions of the flow of thermonuclear fusion.
