NONLINEAR PHYSICAL CHARACTERISTICS OF A HIGH-VOLTAGE ELECTRIC DISCHARGE IN A TWO-PHASE LIQUID K. Kusaiynov and S. E. Sakipova UDC 537.528 Physical features of an electric discharge in a gas-liquid medium are investigated; a direct relationship between the entropy change and the fractal nature of the medium itself is shown. Simplified equations and laws of conservation that describe the dynamics of the electric discharge in the two-phase liquid with allowance for the thermodynamic properties of the medium as functions of its fractal structure are used.
