Abstract: | It is known that in nonuniform magnetic fields the precavitation properties of aqueous media change, leading to an increase in the irreversible physicochemical changes.Notation l length of zone II - D and d diameters of tubes I, III, and II - pI, pII, pIII pressures in regions I, II, and III - pcr critical pressure at which cavitation occurs - p cr and pcr0 critical pressures in the magnetic field and when there is no magnetic field - [VI, VII, VIII] velocities of the liquid in regions I, II, and III - VII, lim velocity of the liquid at which breakdown of the hydrated layer occurs for a certain value of the induction - V cr and Vcr0 critical velocities at which cavitation occurs in the magnetic field and when there is no magnetic field - pa atmospheric pressure - psv saturation-vapor pressure at the given temperature - density of the liquid - kinematic viscosity - Re Reynolds number - Recr critical Reynolds number - cgf and cgd concentrations of free and dissolved gases in the magnetic field and when there is no magnetic field - c gf and c gd, and cgf0 and cgd0 concentrations of free and dissolved gases in the magnetic field and when there is no magnetic field - sc space-charge density - electrical conductivity in the volume of the liquid - b electrical conductivity in the boundary layer - l, g, d dielectric constants of the liquid in the volume, of the gas in the bubbles, and of the diffusion layer - j, jb, ji, and jT current density of the general, boundary layer, induced and current flow - fMHD and fEHD volume forces of magnetohydrodynamic and electrodynamic nature (per unit volume) - pMHD pressure in the liquid due to the action of the magnetohydrodynamic forces - 0 limiting shear stress in the liquid - B magnetic induction - E electric field strength in the volume of the liquidTranslated from Inzhenerno-Fizicheskii Zhurnal, Vol. 35, No. 5, pp. 842–850, November, 1978. |
