The effect of the finite electrical conduction (finiteness of the magnetic Reynolds number), which is considered a dissipative factor, on small natural oscillations of an ideal heavy liquid of finite depth whose free surface borders on vacuum is studied. A constant external horizontal magnetic...
The nonlinear problem of charge exchange between an ion flow and neutral particles is considered. An exact solution of the equations of charge-exchange interaction in plane geometry is found. Parameters determining the effectiveness of interpenetration of dense flows and the structure of the...
The excitation of light emission of the 0-0 band of the first negative system of the nitrogen ion by activation of nitrogen molecules using short pulses of fast electrons was studied. The intensity and width of the light response were measured as functions of the duration and amplitude of the...
The physical and mathematical principles of the method of electrogas-and electrohydrodynamic conversion of electrical signals to pneumatic (hydraulic) signals and vice versa for control of gas and liquid jets and flows in electropneumohydraulic systems are considered.
The functional dependence of the coefficient of ultimate elongation on the temperature of initial heating of the jet-forming layer of shaped-charge liners is obtained. It is established that heating of the shaped-charge liner material before initiation increases the ultimate elongation and,...
A physicomathematical model of superdeep penetration taking into account the strength properties of the target is proposed. Based on this model, the problem of superdeep penetration of tungsten particles into a steel target has been solved for the first time.
Results of an experimental study of the high-rate (400–1200 m/sec) interaction of spherical aluminum particles with a surface are given. Particle deformation was studied by means of a microscope. The mean values of the degree of particle strain were determined by statistical processing for...
The conditions of development of bubble cavitation in liquid media upon shock-wave loading are found. It is s shown that, for the development of an unbounded cavitation, the bubbles should grow to certain critical sizes sufficient for their transition to a nonequilibrium state owing to the...
The effect of shock waves on gas absorption by liquid in bubbly media with different degrees of gas solubility is studied. It is shown that a shock wave acting on a gas-liquid medium can significantly enhance the mass transfer between the gas and the liquid.
The problem of exhaustion of a thin film of a non-Newtonian fluid with a power rheological law from a slotted orifice is solved with account of film slipping relative to the underlying surface. By the method of group analysis with transformation of the parameters entering the problem, an...
