In this paper, a semi-Markovian random walk process (X(t)) with a discrete interference of chance is constructed and the ergodicity of this process is discussed. Some exact formulas for the first- and second-order moments of the ergodic distribution of the process X(t) are obtained, when the...

The numerical solution of complex heat exchange with account of phase transitions in secondary contour is obtained. Temperature, pressure and evaporation distributions along height of a heat exchanger and parametrical dependences of phase transitions boundaries on initial conditions are found.

Technologycal scheme of electric energy obtaining on the basis of thermal water is suggested. The method of optimal regime calculation is presented. Some parametries of Daghestan Geothermal power plant are presented.
