Necessary And Sufficient

The phenomenological model of microcracks evolution in laminated rocks was developed under an isothermal approximation. The general form of the constitutive relations of porous media with microcracks was obtained. This form is necessary and sufficient for carrying out the principle of objectivity and the principle of thermodynamic consistency. The approximation of infinitesimal deformations of medium was investigated. The elastic potential of transversal isotropic brittle rocks was constructed. It involves latent energy of damage and terms which characterize elastic energy release due to damage evolution.

Natural Gas Flow

The flow of wet natural gas in the pipeline is considered in the presence of the formation of gas hydrates on the internal walls of the channel. In the description of the phenomenon, such interrelated processes as phase transformations and mass transfer of water into the composition of gas hydrates, heat transfer between the gas stream and the environment, heat conductivity in the ground are taken into account.
