T., Registration Date 09-02-2007 Organization The Institute of Hydromechanics of the National Academy of Sciences of Ukraine popup.description2 The mechnical-acoustic, hydro- and thermodynamic properties are described for a number of heterogeneous composite and dispersed systems that contain a gas or liquid fraction. The investigation was based on the conception of mechanics of continua with the allowance for coupling between the fields having different nature and using the space- and time-averaging techniques and probabilistic approaches; the modeling experiments were conducted. In particular, normal wave properties of elastic-liquid waveguides are characterized; the model of forming the acoustic properties for gas-liquid dispersed systems is developed with the allowance for a local thermal interaction on microstructure level; near-wall behavior of the flow of a viscous incompressible fluid in the vicinity of a cavity is studied; the behavior of multiphase turbulent flows with dispersed solid particles having finite dimensions is modeled; features of field formation for internal waves scattered on the liquid intrusion inhomogeneties are studied; generalized motion equations for inhomogeneous magneto-elastic and megneto-hydrodynamic media are developed and solved at various values of electric conductivity.
