The Bogoliubov method of canonical transformations is used to study the magnetoelastic waves in long-period modulated structures. The dispersion equation for a magnetoelastic wave and the parameters of magnetoelastic interaction for variable directions of propagation of a coupled wave are found. The effect of I 1/I ratio on the value of a dimensionless constant of magnetoelastic interaction is examined. © 2011 Allerton Press, Inc.

The theory of heat exchange in axial-symmetry turbulent flow in a well is developed with the help of modification of an asymptotic method. Based on analysis of the zero coefficient, the cross-section temperature values are shown to be independent of the flow structure. The contribution of the velocity field and turbulent heat conduction determines the temperature radial distributions, which are calculated based on the first coefficient of asymptotic expansion. © 2013 Pleiades Publishing, Ltd.

The process of formation of a gas hydrate in a finite-length porous medium partially saturated with water, which is purged by a cold gas, is studied. The influence of the initial parameters of the porous medium and purging conditions on the evolution of hydrate saturation and temperature is examined. © 2011 Pleiades Publishing, Ltd.
